= – 1 is a solution of the equation (a) x – 5 = 6                (b) 2x + 5 = 7                (c) 2(x – 2) + 6 = 0                (d) 3x + 5 = 4

c) 2(x-2)+6=0

2(x-2)+6=0

Distribute

2x - 4 + 6 = 0

Combine like terms -4 + 6

2x + 2 = 0

Subtract both sides

2x = -2

Divide both sides

x = -1

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!

the function makes a strait line horizontally with no x intercept but a y intercept at 9.
