Answer:
The first graph represents y<2x-3
For this use some values for x e.g
X= 2 2(2)-3=y=1
So when x is 2 y is 1 so search for the graph that crosses the coordinate (2,1)
Which is graph A
Answer:

Step-by-step explanation:
Look at the picture.

Divide y by x:
150/10 = 15
135/9 = 15
30 /2 = 15
They all equal 15
This means the constant of proportionality would be y = 15x
The answer is C.
Answer:
x = 3
Step-by-step explanation:
7x - 9 + 3x = 2x + 18 - x
10x - 9 = x + 18
10x - x = 18 + 9
9x = 27
x = 3

answer is
</span>-3x^2 +6
hope that helps
