Answer:

gradient = \(\frac{3}{2}\) , y- intercept = \(\frac{5}{2}\)

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the gradient and c the y- intercept )

given

2y - 3x = 5 ( add 3x to both sides )

2y = 3x + 5 ( divide through by 2 )

y = \(\frac{3}{2}\) x + \(\frac{5}{2}\) ← in slope- intercept form

with gradient m = \(\frac{3}{2}\) and y- intercept c = \(\frac{5}{2}\)

The gradient is:

The y intercept is:

Work/explanation:

Let's rearrange the equation first so that it's in slope intercept.

Our equation is

\(\bf{2y-3x=5}\)

And we should write it in \(\bf{y=mx+b}\) form. Let's go ahead and perform the required operations.

________________________

Add 3x on each side:

\(\bf{2y=5+3x}\)

\(\bf{2y=3x+5}\)

Now, divide each side by 2:

\(\bf{y=\dfrac{3}{2}x+\dfrac{5}{2}}\)

This is the equation in slope intercept.

As for the gradient, that is the number in front of x : 3/2.

As for the y intercept, that is the constant : 5/2

Hence, these are the answers.

Answer:

C. 395.1

Step-by-step explanation:

Substitute the value for x:

\(V=0.95(8)^{2.9}\\V=395.1\)

Answer:

\(y = -7\)

\(y = 3\)

\(y = 13\)

\(y = 53\)

The slope of the line is 2.

The slope is going up from left to right, so it'll be positive to start with. From there you have to do rise over run. That is pretty much how many units up and in towards the slope do you have to go until you find 2 points that are in the center of the line. In this case, the rise over run is 2/1 which equals 2.

If values prοvided then transfοrmatiοn οf vectοrs can be determined.

In mathematics, a vectοr is a mathematical οbject that represents a quantity with bοth a magnitude and a directiοn. Vectοrs can be used tο represent physical quantities such as velοcity, fοrce, and acceleratiοn, as well as mοre abstract cοncepts such as cοlοr, sοund, and temperature.

Withοut seeing the figure οr the values οf a1, a2, and a3, it is nοt pοssible tο determine whether the specified linear transfοrmatiοn T : R2 → R2 is οne-tο-οne and οntο.

Hοwever, in general:

A linear transfοrmatiοn T : Rn → Rm is οne-tο-οne if and οnly if its kernel (i.e., the set οf vectοrs that are mapped tο the zerο vectοr) is trivial, meaning that the οnly vectοr that maps tο the zerο vectοr is the zerο vectοr itself.

A linear transfοrmatiοn T : Rn → Rm is οntο if and οnly if its range (i.e., the set οf all vectοrs that can be οbtained by applying T tο sοme vectοr in Rn) is equal tο Rm.

Tο determine whether a linear transfοrmatiοn is οne-tο-οne οr οntο, we can examine its prοperties and characteristics, such as its kernel, range, rank, and determinant. We can alsο use geοmetric intuitiοn and visualizatiοn tο understand hοw the transfοrmatiοn maps pοints and vectοrs in Rn tο Rm.

If yοu prοvide mοre infοrmatiοn abοut the values οf a1, a2, and a3 and the figure that shοws the standard matrix A, it can help yοu determine whether the transfοrmatiοn is οne-tο-οne and οntο and draw the image οf the vectοr [-1, 1] under the transfοrmatiοn T.

Step-by-step explanation:

The dolphin's weight that differs most from the value predicted by this model is JoJo's (31 lb of difference)

Let's elaborate the model this way:

Snowflake's length - Pax's length = 8.2 - 7.6 = 0.6 ft

Snowflake's weight - Pax's weight = 549 - 519 = 30 lb

Ratio = 30/0.6 = 50 lb/ft

This means that for every foot of length, the dolphin has a variable weight of 50 lb.

However, if we multiply the ratio by the actual length of the two dolphins, we will have these results:

Snowflake = 50 × 8.2 = 410

Pax = 50× 7.6 = 380

Snowflake = Actual weight - Ratio× Length = 549 - 410 = 139

Pax = Actual weight - Ratio × Length = 519 - 380 = 139

The common difference is 139.

Therefore, the linear model that predicts the weight (y) of a dolphin given its length (X) is:

y = 139 + 50x

Now, let's use the linear equation or model to calculate the weight of the remaining four dolphins, as follows:

Blaze  y = 139 + 50 × 6.8 = 479 ⇒ difference of 9 lb (488 - 479)

JoJo   y = 139 + 50 × 5.8 = 429 ⇒ difference of 31 lb (460 - 429)

Corky   y = 139 + 50 ×8.4 = 559 ⇒ difference of 2 lb  (559 - 557)

Shadow  y = 139 + 50 × 7.4 = 509 ⇒ difference of 8 lb  (509 - 501)

Hence, the dolphin's weight that differs most from the value predicted by this model is JoJo's (31 lb of difference)

The paint should be used is Cloudy Sunrise.

As a fraction of 100, a percentage is a number or ratio. The abbreviations "pct.", "pct.", and occasionally "pc" are also used to indicate it, while the percent symbol, "%," is most frequently employed. A % has no dimensions and no associated unit of measurement.

Light-at-Dawn: A 1-gallon can normally costs $24, however it is now on sale for 25% less than that amount. This kind of paint needs two coats.

Cloudy Sunrise: A gallon-sized can costs $28. Only one coat of this kind of paint is necessary.

350 square feet will be covered by each gallon at a time.

The price of 1 gallon of light at dawn is 24 - 25/100 * 24 = 18.

1 gallon of clouded sunrise color costs 28 dollars.

It appears overcast. Prior to accounting for the number of square feet that each hue may cover, sunrise color is more expensive.

350 square feet are claimed to be covered by both cans.

if everything else remains the same,.

Dawn color lighting would cost:

18 / 350, or.0514285714, per square foot.

However, the light at dawn color needs two coats.

The total cost per square foot for the light at dawn color would be

2 * 0.0514285714 = 0.1028571429.

The price of a cloudy sunrise is 28/350 = 0.08 per square foot.

This represents the total cost per square foot for cloudy sunrise color since it only needs one coat.

It looks that the total cost of cloudy sunrise color is less expensive than the total cost of light at dawn color, assuming that the second coat of paint uses the same amount of paint as the first coat.

Hence, The paint should be used is Cloudy Sunrise

Rational numbers

Explanation:

A rational number can be made by dividing two whole numbers.

So if we look at the given set of numbers below, they all can be written as fractions. For example,

-36 = -36/1

-15 = -15/1

10 = 10/1

(-36, -15, 9/100, 9/4, 10, 25)

The statement about function g which is true is that: function g is exponential because g(x) changes by equal factors over equal intervals of x.

The slope of a line simply refers to the gradient of a line and it's typically used to describe both the ratio, direction and steepness of an equation of a straight line.

Mathematically, the slope of a straight line can be calculated by using this formula;

\(Slope = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}\)

Slope = (40 - 10)/(2 - 1)

Slope = 30/1

Slope = 30

Slope = (160 - 40)/(3 - 2)

Slope = 120/1

Slope = 120.

Factor = 40/10 = 4

Factor = 160/40 = 4

Factor = 640/160 = 4.

Therefore, function g is exponential because g(x) changes by equal factors over equal intervals of x.

Answer: 8k^2 - 19k + 12

Step-by-step explanation: The way we found this answer was by simplifying the expression.

Step 1 : We want to get (x-2) in the numerator so we could cross it out with the x-2 at the bottom to get our simplified expression.

(8k^3-19k^2+2k+10)/(k-2) = (x-2)(8k^2-17k+5)/(x-2)

You would need to factor out the (x-2)

Step 2: When you cross the (x-2) above with the (x-2) below you end up with 8K^2-17k+5 as the answer.

Answer:

1. See what multiplies with the first term in the divisor to get the first term in the dividend. Then, put that answer in the quotient space.

2. Under the first term in the dividend, write a - sign and open parentheses. Put the first term inside the parentheses.

3. Multiply what you put in the quotient space from step #1 with the second term in the divisor.

4. Put the product from step #3 inside of the parentheses.

5. Subtract the first two terms in the parentheses from the first two terms in the dividend.

. . . . . . . . . . . . . note: in polynomial division, you will not always subtract two terms. we are subtracting two terms here because there are two terms in the divisor.

6. Write the answer from #5 under the parentheses, and bring down another term from the dividend.

7. See what multiplies with the first term in the dividend to get the answer from #5. Then, put that answer in the quotient space.

8. Under step #6, write a - sign and open parentheses. Put the answer from #5 inside the parentheses.

9. Multiply the answer from #7 with the second term in the divisor.

10. Next to the answer from step #8, write the product of step #9.

11. Subtract the terms from step #10 from step #6.

12. Repeat until you have "brought down" all of the terms from the dividend.

After you are done, your remainder will not be 0. Instead, it will be +2. When you have a remainder that isn't 0, you cannot use the quotient as your answer. Instead, you have to write your answer in this format:

\(q(x)+\frac{r(x)}{d(x)}\), where q(x) is the quotient, r(x) is the remainder, and d(x) is the divisor.

⇒ q(x) = \(8k^2-3k-4\)

⇒ r(x) = +2

⇒ d(x) = k -2

⇒ \(8k^2-3k-4+\frac{2}{k-2}\)

Answer:

The selling price of the diamond necklace at Shamin Jewelers after 10% discount is:

$442 * 0.9 = $397.80

The selling price of the same necklace at the competitor's store after 34% and 14% discount is:

$527 * 0.66 * 0.86 = $247.08

So, Shamin Jewelers needs to offer an additional discount to meet the competitor's price:

$397.80 - $247.08 = $150.72

To calculate the additional rate of discount, we divide the difference by the original selling price at Shamin Jewelers and multiply by 100:

($150.72 / $442) * 100 = 34.11%

Therefore, Shamin Jewelers must offer an additional 34.11% discount to meet the competitor's price.

Average of Syed on 5 assignments, A=91%.

Ms. Crockett has gotten a 91%, 70%, 99%, 81% on the first four assignments.

Let a be the average of Ms. Crockett.

Let x be the grade got by Ms. Crockett on the fifth assignment.

Now, the average of Ms. Crockett can be expressed as,

Crockett has to get an average above 91% to beat Ms. Syed.

To find the score x, Ms. Crockett should get in the fifth assignment to beat Syed, put a=91% in the above equation.

So, Ms. Crockett should get a score greater than 114% to overcome Ms. Syed's average.

But, it is mathematically impossible to get 114%. Hence, Ms. Crockett cannot beat Ms. Syed.
