(2x − 12) = −28

a)
−18

b)
−29

c)
−32

d)

−9

B)  

−29

Step-by-step explanation:

2/5(2x − 12) = −28  

Multiply each side by 5/2 to clear the fraction

5/2*2/5(2x − 12) = −28*5/2

2x-12 = -70

Add 12 to each side

 2x-12+12 = -70+12

2x = -58

Divide by 2

2x/2 = -58/2

x = -29

step-by-step explanation:

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
