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:
1/4
Step-by-step explanation:
Expand
f(x)=-1x^2-8x+33
x coordinate of vertex is -b/2a in the form ax^2+bx+c=y
a=-1
b=-8
-(-8)/2(-1)=8/-2=-4
plug back in to get y value
y=-(-4^2)-8(-4)+33
y=-16+32+33
y=49
y value is 49
Answer:
-52
Step-by-step explanation:
-18+6=-12
-12-40=-52
