Answer:

match the boxes to the parts of the equations shown below

Step-by-step explanation:

$\text{slope}=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{50-34}{5-3}=\dfrac{16}{2}=8$

<h3>Right</h3>

$\text{slope}=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{2-31}{30-1}=\dfrac{-29}{29}=-1$

alisha [4.7K]

Step-by-step explanation:

Use formula to find the slope/gradient

$\frac{y2 - y1}{x2 - x1}$

(-5, -1) = (x1, y1)

(5, 11) = (x2, y2)

So,

$= \frac{11 - ( - 1)}{5 - ( - 5)} \\ = \frac{12}{10 } \\ = \frac{6}{5}$

In a certain year, there were 88 female officials in Congress, which is comprised of the House of Representatives and the Senate

Ainat [17]

Answer:

71 in House of Representatives
17 in Senate

Step-by-step explanation:

Let h and s represent the numbers in the House and Senate, respectively. Then we have ...

h + s = 88

h - s = 54

Subtracting the second equation from the first gives ...

(h +s) -(h -s) = (88) -(54)

2s = 34 . . . . . simplify

s = 17 . . . . . . . divide by 2

h = 88 -17 = 71 . . . . find the other value using the sum equation

There were 71 females in the House of Representatives, and 17 females in the Senate.

If a= .75 and b= .50, what is the perimeter of the rectangle?

Lerok [7]

Answer:

C. 14 inches

Step-by-step explanation:

The perimeter is double the sum of length and width:

P = 2((4a +3) +(6b -2) = 8a +12b +2

For the given values, this is ...

P = 8(0.75) +12(0.50) +2 = 6 + 6 + 2 = 14

The perimeter is 14 inches.

For one child, a childcare facility charges $350 per month for preschool and $5.00 per hour for each additional hour for after-s

Hatshy [7]

Answer:

D. 80

Step-by-step explanation:

We have the following function :

$f(h)=350+5h$ (I)

Where $f(h)$ is the monthly fee for after - school care and preschool.

Where $h$ represents the number of hours spent in after - school care.

We know that the total monthly bill for one child was $750 ⇒

$f(h)=750$

Using (I) we will find the value of the hours '' $h$ '' that verifies the expression ⇒

$f(h)=750=350+5h$ ⇒

$750=350+5h\\750-350=5h\\400=5h\\h=\frac{400}{5}=80$

We find that the value of the hours '' $h$ '' is 80 hours.

The total number of hours the child spent in after - school care is D. 80
