Answer: 62.5 yards

Step-by-step explanation:

So we can make a ratio:

2 minutes : 25 yards

2:25

Simplify:

1:12.5

Times 5 by 1 minute to get 5 minutes

Whatever you do to one side do to another

5:62.5

62.5 yards

Q6.

The slope-intercept form: y = mx + b

m - slope

b - y-intercept

We have: slope m = 3, y-intercept (0, 4) → b= 4

<h3>Answer: y = 3x + 4</h3>

Q7.

2x + 4y = 4 |subtract 2x from both sides

4y = -2x + 4 |divide both sides by 4

y = -0.5x + 1

Only second graph has y-intercept = 1.

<h3>Answer: The second graph.</h3>

Q8.

The point-slope form:

$y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}$

We have

$(-16,\ 8)\to x_1=-16,\ y_1=8\\(4,\ -2)\to x_2=4,\ y_2=-2$

Substitute:

$m=\dfrac{-2-8}{4-(-16)}=\dfrac{-10}{20}=-\dfrac{1}{2}\\\\y-8=-\dfrac{1}{2}(x-(-16))\\\\y-8=-\dfrac{1}{2}(x+16)$

<h3>Answer: The first equation.</h3>

Q9.

It's a vertical line. The equation of a vertical line is x = <em>a</em>, where <em>a</em> is any real number.

<h3>Answer: x = -4</h3>

Clare volunteers at a local library during the summer. Her work includes putting labels on 750 books. How many minutes will she

Lubov Fominskaja [6]

Answer:

75 minutes

Step-by-step explanation:

Assuming that Clare will not take a break throughout the session

10 books=1 minute

750 books= x minutes

Cross multiplying to find the value of x

10x books=750 books minutes

Making x the subject

x=750 books minutes/(10 books)

x=75 minutes

This translates to 1 hours and 15 minutes

Therefore, Clare will require 75 minutes
