Step-by-step explanation:

1d

2c

3a

4c

6  4=110(alt exter) 3=70(Suppl of 4)   1=70(vertical with 3)

7    x=3

   8x+8=32

8x=24

x=3

8

42=8x-14

56=8x

x=7

42=56-14

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
