4. April rewrote a quadratic function in vertex form. h(x) = 5x2 – 30x + 30
Step 1: h(x) = 5(x2 - 6x+ ) + 30
Step 2: h(x) = 5(x2 - 6x + 9) + 30 – 45
Step 3: h(x) = 5(x - 3)2 + 15
April said that the vertex is (3,15). Is April correct? If not, identify the step
in which April made the mistake and correct her work.

If the equation is "9+(1/2)4=x" Then the correct answer would be 11.

Step-by-step explanation:

9+(1/2)(4)=x

Multiple 4 times 1/2 which is the same as dividing by 2.

You now have 9+2.

9+2=11
