Answer:

x = -7.33        OR         x = \(\frac{-22}{3}\)

y = 13

Step-by-step explanation:

→You can use the substitution method. First, make y by itself in (-2 + 2y = 24):

-2 + 2y = 24

2y = 26

y = 13

→Then, plug in 13 for y into the other equation:

3x + 2y = 4

3x + 2(13) = 4

3x + 26 = 4

3x = -22

x = -7.33        OR         x = \(\frac{-22}{3}\)

The properties or relationship between the angles m∠1, m∠2, and m∠3 can be used to determine the statement that must be true

The correct option that gives the statement that must be true to prove that m∠1 + m∠2 + m∠3 = 180°, is the first option

A. m ║ n

Reason:

Which statement must be true to prove that m∠1 + m∠2 + m∠3 = 180°?

A. m ║ n

B. m∠1 + m∠2 = 180° - m∠3

C. m∠1 + m∠2  = 90°

D. m∠1 = m∠2 = m∠3

Given that m∠1 + m∠2 + m∠3 = 180°, we have;

m∠ACD + m∠2 + m∠3 = 180° by angles on a straight line

Therefore;

m∠ACD = m∠1 by addition property of equality

m∠ACD ≅ m∠1 by definition of congruency

m∠ACD and m∠1 are alternate interior angles formed between lines m and n and their common transversal AC

Which gives;

m ║ n, by alternate interior angles theorem which states that alternate interior formed between parallel lines are congruent

Therefore;

The statement that must be true to prove that m∠1 + m∠2 + m∠3 = 180°  is m ║ n

Answer:

f(3)=275, f(5)=325

Step-by-step explanation:

We just plug in 3 and 5 into the equation:

We get f(x) = 25x + 200

f(3) = 25*3 + 200

=75+200

=275

Interpretation: if there are three cell phones on the plan, then the total monthly cost is 275.

for f(5):

f(5) = 25*5 + 200

=125+200

=325

Interpretation: if there are five cell phones on the plan, then the total monthly cost is 325.

Answer:

f(3)= 75, which is the cost of a cell phone plan with 200 phones for 275 a month;

f(5)= 125, which is the cost of a cell phone plan with 200 phones for 325 a month;

Answer:

The number of packs is 5.

Step-by-step explanation:

Let the number of juicy packs of gum bought by Marisol be represented by n.

Adeline bought 8 packs of Fun gum with each pack containing 7 pieces of gum.

Total number of gums has Adeline = 8 x 7

                                                          = 56

Total pieces of gum has Marisol = n x 9

                                                      = 9n

Given that Adeline has 11 more pieces of gum than Marisol, thus;

56 = 9n + 11

56 - 11 = 9n

45 = 9n

n = \(\frac{45}{9}\)

n =  5

The number packs of juicy gum bought by Adeline is 5 and total pieces of his gum is 45.

The actual area of her office is 50 ft squared.

The blueprint for Zahra's new office measures 4 cm long and 2 cm wide.

The scale for the blueprint is 6 cm to 15 ft.

let's convert the units using the scale

6 cm = 15 ft

4cm = ?

cross multiply

length = 4 × 15 / 6

length = 60 / 6 = 10 ft

6 cm = 15 ft

2 cm = ?

cross multiply

width = 2 × 15 / 6

width = 30 / 6 = 5 ft

Therefore,

Answer:

A. 30.144

Step-by-step explanation:

This is a Chi-Squared test

Given:

To use the Chi-Square distribution table, you need to know two values:

Degrees of Freedom = n - 1 = 20 - 1 = 19

The significance level is 5%, so \(\alpha= 0.05\)

This is a one-tailed test since \(\textsf{H}_1:\sigma^2 > 384\) so Upper tail area = 0.05

Reading from the table (attached), the critical value is:  30.144

(This means that we reject \(\textsf{H}_0\) if the test statistic is greater than 30.144)

There is no change in its slope as initial and final slope is 1.

What is slope?

In arithmetic, the slope or gradient of a line may be a variety that describes each the direction and therefore the abruptness of the line.

Main body:

formula for slope with two points form is =

y -y₁ =( y₂-y₁ /x₂-x₁ )(x - x₁)

according to question ,

points are (0,0) and (3,3)

y - 0 = (3-0/3-0)(x -0)

y = 3/3 *x

y = x

hence slope of line is 1.

Now points are (0,0) and (-3,-3).

y - 0 = (-3-0/-3-0)(x -0)

y =- 3/-3 *x

y = x

hence slope of line is 1.

So there is no change in its slope.

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

We can think of this problem like a triangle that Tom, Blair, and Marcia live in.

This triangle is a right triangle.

the opposite is 3, the hypotenuse is 7, and the adjacent side is unknown.

Solving for the adjacent side will give us the distance that Tom and Blair live from each other

a^2 +b^2 = c^2

3^2 + b^2= 7^2

Now we solve for B

7^2 =49

3^3=9

9+b^2=49

Now we subtract

49-9=40

9+40=49

The square root of 40 is 6.3246

Now we check our work

3^2 +6.32^2=7^2

9+ 40 =49

The answer is, tom and Blair live approximately 6.3246 blocks from each other

The vertex form of the quadratic equations in standard form are, respectively:

Case 9: y = 2 · (x + 2)² - 12

Case 10: y = - (1 / 2) · (x + 3 / 4)² + 33 / 32

Case 11: y = 3 · (x - 4 / 3)² - 16 / 3

Case 12: y = - 3 · (x - 3)²

Case 13: y = (x - 4)² + 3

Case 14: y = (x - 1)² - 7

Case 15: y = (x + 3 / 2)² - 9 / 4

Case 16: 2 · (x + 1 / 4)² - 1 / 8

Case 17: y = 2 · (x - 3)² - 7

Case 18: y = - 2 · (x + 1)² + 10

In this problem we find ten cases of quadratic equation in standard form, whose vertex form can be found by a combination of algebra properties known as completing the square. Completing the square consists in simplifying a part of the quadratic equation into a power of a binomial.

The two forms are introduced below:

Standard form

y = a · x² + b · x + c

Where a, b, c are real coefficients.

Vertex form

y - k = C · (x - h)²

Where:

Now we proceed to determine the vertex form of each quadratic equation:

Case 9

y = 2 · x² + 4 · x - 4

y = 2 · (x² + 2 · x - 2)

y = 2 · (x² + 2 · x + 4) - 12

y = 2 · (x + 2)² - 12

Case 10

y = - (1 / 2) · x² - 3 · x + 3

y = - (1 / 2) · [x² + (3 / 2) · x - 3 / 2]

y = - (1 / 2) · [x² + (3 / 2) · x + 9 / 16] + (1 / 2) · (33 / 16)

y = - (1 / 2) · (x + 3 / 4)² + 33 / 32

Case 11

y = 3 · x² - 8 · x

y = 3 · [x² - (8 / 3) · x]

y = 3 · [x² - (8 / 3) · x + 16 / 9] - 3 · (16 / 9)

y = 3 · (x - 4 / 3)² - 16 / 3

Case 12

y = - 3 · x² + 18 · x - 27

y = - 3 · (x² - 6 · x + 9)

y = - 3 · (x - 3)²

Case 13

y = x² - 8 · x + 19

y = (x² - 8 · x + 16) + 3

y = (x - 4)² + 3

Case 14

y = x² - 2 · x - 6

y = (x² - 2 · x + 1) - 7

y = (x - 1)² - 7

Case 15

y = x² + 3 · x

y = (x² + 3 · x + 9 / 4) - 9 / 4

y = (x + 3 / 2)² - 9 / 4

Case 16

y = 2 · x² + x

y = 2 · [x² + (1 / 2) · x]

y = 2 · [x² + (1 / 2) · x + 1 / 16] - 2 · (1 / 16)

y = 2 · (x + 1 / 4)² - 1 / 8

Case 17

y = 2 · x² - 12 · x + 11

y = 2 · (x² - 6 · x + 9) - 2 · (7 / 2)

y = 2 · (x - 3)² - 7

Case 18

y = - 2 · x² - 4 · x + 8

y = - 2 · (x² + 2 · x - 4)

y = - 2 · (x² + 2 · x + 1) + 2 · 5

y = - 2 · (x + 1)² + 10

The domain of the function f(x) that has a range of [-2, ∞) is [-2, ∞)

The inverse of a function that maps x into y, maps y into x.

The given coordinates of the points on the radical function, f(x) are; (-3, -2), (1, 0), (6, 1)

To determine the domain of

\( {f}^{ - 1}( x)\)

The graph of the inverse of a function is given by the reflection of the graph of the function across the line y = x

The reflection of the point (x, y) across the line y = x, gives the point (y, x)

The points on the graph of the inverse of the function, f(x), \( {f}^{ - 1} (x)\) are therefore;

\(( - 3, \: - 2) \: \underrightarrow{R_{(y=x)}} \: ( - 2, \: - 3)\)

\(( 1, \: 0) \: \underrightarrow{R_{(y=x)}} \: ( 0, \: 1)\)

The coordinates of the points on the graph of the inverse of the function, f(x) are; (-2, -3), (1, 0), (1, 6)

Given that the coordinate of point (x, y) on the image of the inverse function is (y, x), and that the graph of the function, f(x) starts at the point (-3, -2) and is increasing to infinity, (∞, ∞), such that the range of y–values is [-2, ∞) the inverse function, \( {f}^{ - 1}( x)\), which starts at the point (-2, -3) continues to infinity, has a domain that is the same as the range of f(x), which gives;

Mr. Casey's class raised $448 during the fundraiser.

Percentage is simply number or ratio expressed as a fraction of 100.

Given that, Ms. Dawson’s class raised $560, which is 25% more than Mr. Casey’s class raised.

To determine ​how much Mr. Casey’s class raised,

We represent the amount raised by Mr. Casey's class as "x".

Since Ms. Dawson's class raised 25% more than Mr. Casey's class.

To calculate 25% more than x, we can multiply x by 1.25

(since 25% is equivalent to 0.25 in decimal form and 100% is 1) and set it equal to $560.

Hence:

1.25x = 560

To solve for x, we divide both sides of the equation by 1.25:

x = 560 / 1.25

x = 448

Therefore, Mr. Casey's class raised $448.
