Answer:

x = -7

Step-by-step explanation:

you have to distribute the 2 to what is in the parenthesis, then you get left with 2x+18=4 so subtract the 18 from both sides leaving you with 2x=-14 so you divide both by 2 leaving you with x=-7.

Which equation represents y= -x^2 + 6x + 7 in vertex form ?

Drupady [299]

we are given

$y= -x^2 + 6x + 7$

we can use vertex form parabola formula

$y= a(x-h)^2+k$

so, we can complete x square

$y= -(x^2 - 6x - 7)$

$y= -(x^2 - 6x - 7+3^2-3^2)$

$y= -(x^2 - 6x +3^2-16)$

$y= -(x-3)^2+16$

so, option-A........................Answer
