Question

Please help c:

Solve 2sqrt x+7 – 10 = –8

x = –6

x = –4

x = 32

x = 74

Answer 1

\[2\sqrt{x+7}-10=-8\]

Answer 2

Yup

Answer 3

Which quadratic equation has a vertex of (0, 5)?

y = (x – 5)2

y = (x + 5)2

y = x2 – 5

y = x2 + 5

Answer 4

Answer 5

The vertex form of a quadratic equation is:
y = a(x-h)²+k

where -(h) is the x-coordinate and (k) is the y-coordinate. So, if you plug this point into the formula, you get:
y = a(x-0)²+5

Since the value of (a) is unknown and irrelevant to the question, it can be assumed to be 1.
simplified:
y = x²+5

Answer 6

first add 10\[2\sqrt{x+7}=2\]
\[\sqrt{x+7}=1\]
\[(x+7)=1^2\]
x=-6
