Divide the top number by the bottom number
This would be easy if you made more sense out of the question.
Answer:
4x - 12 = 28
To isolate 4x, we add 12 to both sides:
4x - 12 + 12 = 28 + 12
so
4x = 40
Now we divide 4 from both sides:
x = 40 / 4
so x = 10
Answer:
f(-2) = 3
Step-by-step explanation:
Look at the graph when x = -2, f(-2) = 3
