Answer:

y = 32

Solving Way #1:

    This way uses the "tip" they give us of finding the relation between the first two values and then applying it to the second x.

    k = \(\frac{y}{x}\)

    2 = \(\frac{16}{8}\)

        -

     y = kx

     y = (2)(16)

     y = 32

Solving Way #2:

    Since they vary directly which each other, we can set up a proportion to solve. I have y values on the top and x values on the bottom.

    \(\frac{16}{8} =\frac{y}{16}\)

    256 = 8y

    32 = y

    y = 32

     Either way, when x is 16 y is 32.

The value of the piecewise function for f(3) is 4

From the question, we have the following parameters that can be used in our computation:

f(x) = 2x if x < 1

f(x) = 1/2x + 5/2 if x >= 1

The function f(3) implies that we make use of the function

f(x) = 1/2x + 5/2

This is because it is valid for x >= 1

substitute the known values in the above equation, so, we have the following representation

f(3) = 1/2 * 3 + 5/2

Evaluate

f(3) = 4

Hence, the piecewise function for f(3) is 4

The graph will cross the x-axis if the multiplicity of the real root is odd.

What is polynomial?

In arithmetic, a polynomial is an expression consisting of indeterminates and coefficients, that involves solely the operations of addition, subtraction, multiplication, and positive-integer powers of variables.

Main body:

For polynomials, the graph will cross the x-axis if the multiplicity of the real root is odd, and just touch the x-axis if the multiplicity of the real root is even. (The multiplicity of the root is the number of times it occurs as a root)

Complex algorithms frequently employ variable words to demonstrate coherence between two opposing assertions. Equations are academic expressions that are used to demonstrate the equality of different academic figures. Consider the information provided by y + 7, when combined with generate y + 7, raising instead produces b + 7 within this situation, as opposed to another technique that could divide 12 into two parts.

Here,

Permit x and y to represent the amount of dimes and nickels, respectively.

Since there are 20 pieces in total, the following is true:

=>  x + y = 20 ...(1)

=>  10x + 5y = 140 ...(2)

We can now solve for x in terms of y using equation (1):

=>  x = 20 - y

When we enter this formula in place of x in equation (2), we obtain:

=>  10(20 - y) + 5y = 140

By enlarging the parentheses and streamlining, we obtain:

=>  200 - 10y + 5y = 140

Further simplification results in:

=>  -5y = -60

When we multiply both parts by -5, we get:

=>  y = 12

To find x, we can solve equation (1) by substituting this number of y. The result is:

=> x + 12 = 20

=>  x = 8

The slope of the line is negative, which means the line slants downward as it moves from left to right.

To sketch the graph of the following given a point and a slope we can follow the following steps:

Step 1: Plot the given point on the coordinate plane.

Step 2: Use the given slope to determine a second point.

The slope is the ratio of the rise over run and tells us how to move vertically and horizontally from the initial point.

Step 3: Connect the two points to create a line that represents the equation with the given slope and point.

P (0, 4); m = 3Since we know the point (0,4) and slope m = 3 ,

we can use slope-intercept form to find the equation of the line.

Slope-intercept form is:y = mx + bwhere m is the slope and b is the

y-intercept.

To find b, we can substitute the given values:

x = 0,

y = 4, and

m = 3y = mx + b4

= 3(0) + bb

= 4

Now we know that the y-intercept of the line is 4,

so we can write the equation as:y = 3x + 4

The graph of this equation is shown below:

The slope of the line is positive, which means the line slants upward as it moves from left to right.

P (2, 3); m = 2

Since we know the point (2,3) and slope m = 2 ,

we can use slope-intercept form to find the equation of the line.

Slope-intercept form is:y = mx + bwhere m is the slope and b is the

y-intercept.

To find b, we can substitute the given values:

x = 2,

y = 3, and

m = 2y

= mx + b3

= 2(2) + bb

= -1

Now we know that the y-intercept of the line is -1, so we can write the equation as:y = 2x - 1

The graph of this equation is shown below:

The slope of the line is positive, which means the line slants upward as it moves from left to right.

P (-3, 5); m = -2Since we know the point (-3,5) and slope m = -2 ,

we can use slope-intercept form to find the equation of the line.

Slope-intercept form is:

y = mx + bwhere m is the slope and b is the y-intercept.

To find b, we can substitute the given values:x = -3, y = 5, and m = -2y = mx + b5 = -2(-3) + bb = -1

Now we know that the y-intercept of the line is -1, so

we can write the equation as:y = -2x - 1

The graph of this equation is shown below:

The slope of the line is negative, which means the line slants downward as it moves from left to right.P (4, 3); m = 3

Since we know the point (4,3) and slope m = 3 , we can use slope-intercept form to find the equation of the line.

Slope-intercept form is:y = mx + bwhere m is the slope and b is the

y-intercept.

To find b, we can substitute the given values:

x = 4,

y = 3, and

m = 3y

= mx + b3

= 3(4) + bb

= -9

Now we know that the y-intercept of the line is -9, so we can write the equation as:y = 3x - 9

The graph of this equation is shown below:

The slope of the line is positive,

which means the line slants upward as it moves from left to right.P (3,-1); m = -4

we can use slope-intercept form to find the equation of the line.

Slope-intercept form is:y = mx + b

where m is the slope and b is the y-intercept.

To find b, we can substitute the given values:x = 3, y = -1, and m = -4-1 = (-4)(3) + bb = 11

Now we know that the y-intercept of the line is 11, so we can write the equation as:y = -4x + 11

M1 . M2 = - 1

Thus, m2 = 2 ( for this equation)

Similarly,

For parallel case,

M1 = m2

Thus, m2 = - 2 ( for this equation)

The estimation of the equation 1/6 + 5/6  is 1 (option C).

For rounding a fraction to the nearest whole number, use the "rounding half up" rule if necessary.

To estimate the solution for the equation 1/6 + 5/6, we can round each fraction to the nearest whole number.

The fraction 1/6 is closer to 0 than it is to 1, so we will round it to 0.

The fraction 5/6 is closer to 1 than it is to 0, so we will round it to 1.

Now we can estimate the solution for the equation as follows:

0 + 1 = 1

Therefore, the estimated solution for the equation 1/6 + 5/6 is 1.

The correct answer is C. 1.

Answer:

The mean weight of an adult is 66 kilograms with a variance of 144. If 123 adults are randomly selected, the sample mean would follow a normal distribution with a mean of 66 kilograms and a standard deviation of sqrt(144/123) = 3/sqrt(123) kilograms.

We can standardize the sample mean to find the probability that it would be greater than 66.7 kilograms. The standardized value for 66.7 is (66.7 - 66) / (3/sqrt(123)) = 2.3094.

Using a standard normal distribution table, we find that the probability of a standard normal variable being greater than 2.3094 is approximately 0.0104.

Therefore, the probability that the sample mean would be greater than 66.7 kilograms is approximately 0.0104, rounded to four decimal places.

Answer:

A) D) g(x) = 2x - 8

2) B) y = 3/4x - 1 and y = -4/3x + 9

Step-by-step explanation:

1)

In the table, we have the points

(5, 2)

(7, 6)

(9, 10)

(10, 12)

This seems to be a linear relationship, so let's try that:

A linear relationship can be written as:

y = a*x + b

where a is the slope and b is the y-axis intercept.

For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:

a = (y2 - y1)/(x2 - x1)

If we use the first two points, we get the slope:

a = (6 - 2)/(7 - 5) = 4/2 = 2

if we use the first and last point, we get the slope:

a = (12 - 2)/(10 - 5) = 10/5 = 2

Then we can conclude that this is a linear relationship with a slope equal to 2.

y = 2*x + b

To find the value of b, we can just replace any of the points of the data table in the equation, for example, i will use the point (5, 2).

this means that x = 5, and  y = 2.

2 = 2*5 + b

2 = 10 + b

2 - 10 = b

-8 = b

Then the equation is:

y = 2*x - 8

the correct option is: D) g(x) = 2x - 8

2) Here we have two lines, notice that we can with just looking at the image, know the y-intercept of each line.

The one with a positive slope (grows to the right) has a y-intercept = - 1.

The one with a negative slope (grows to the left) has a y-intercept =  9.

The two options that match this condition are:

B) y = 3/4x - 1 and y = -4/3x + 9

C) y = 3/4x - 1 and y = -3/4x + 9

Where the only difference is the slope of the black line.

so et's check which slope matches that line.

In the graph we can see that it passes through the points:

(0, 9) and the point (6, 1)

Then the slope is:

a = (1 - 9)/(6 - 0) = -8/6 = -4/3

Then the correct option is where the negative slope is -4/3, that one is

B) y = 3/4x - 1 and y = -4/3x + 9
