A student named CJ wrote the vertex form equation for a quadratic function with a vertex at (2,3) and an -a -value of -1. vertex form: y=a(x+h)^2-k (h, k) = (2,3) a = -1 y= -(x+2)^2 -3. CJ was not correct on this. explain the mistakes .

do i do it on a graph?

step-by-step explanation:

∠cbe and ∠deb are same-side interior angles.

i took the test

what

1. x> -5

2. x< 8

step-by-step explanation:

1. 2x> -10

divide by 2 from both sides of equation.

2x/2> -10/2

simplify, to find the answer.

-10/2=-5

x> -5 is the correct answer.

2. 3x< 24

divide by 3 from both sides of equation.

3x/3< 24/3

simplify, to find the answer.

24/3=8

x< 8 is the correct answer.

i hope this you, and have a wonderful day!
