Answer:
353
Step-by-step explanation:
355-42=x-40
I just need to subtract 2 from 355 to get x because I subtracted 2 from 42 to get 40.
355-2=353=x
Answer:
Slope = -1

Answer:
Step-by-step explanation:
The vertex would be the highest/lowest point so lets factor this first
when we factor we get
2(x^2+6x+8)
2(x+4) (x+2)
Using zero product property we find the 2 x values and x intercepts are
-4 and -2
the middle point of these points is -3
Substitute -3 for x and solve
2(-3+4) (-3+2)
2 * 1 * -1
2*-1
-2
(-3,-2) is the vertex
