Question

I don't know how to do these

Answer 1

okay just follow everything under here!

Explanation:

so y = 5x right? so on the chart, it goes from 1-4. x is those numbers. so in the second column, you see 5x. so you would multiply 5 x __ whatever the number is. so this would be column 2.

5x1

5x2

5x3

5x4

and then the second column is 5, 10, 15, 20

then you do the same thing with the second one.

7x1

7x2

7x3

7x4

then Y would be 7, 14, 21, 28

then number 3, it would be B. 8h = d

8 x h (hours) = 8h which would = d (amount made)

i hope this helped! good luck!

Answer 2

1. Below 2. B. d = 8h

Explanation:

The graph is a bit confusing. But basically, substitute x for the numbers they give you.

5x

5 · 1 = 5 = y

5 · 2 = 10 = y

5 · 3 = 15 = y

5 · 4 = 20 = y

7x

7 · 1 = 7 = y

7 · 2 = 14 = y

7 · 3 = 21 = y

7 · 4 = 28 = y
