Answer:

$\Large \boxed{\sf \bf \ \ y=4(x-5)^2-12 \ \ }$

Step-by-step explanation:

Hello, please consider the following.

$\dfrac{1}{4}(y + 12) = (x - 5)^2\\\\\text{We multiply by 4 both sides of the equation.}\\\\y+12=4(x-5)^2\\\\\text{We subtract 12 from both sides of the equation.}\\\\y=4(x-5)^2-12=a(x-h)^2+k$

So a = 4, h = 5 and k = 12

Hope this helps.

Do not hesitate if you need further explanation.

Answer:

10 2/3 x 9/10 = 9 3/5

1 x 10 2/3 = 10 2/3

10 2/3 x 2 1/3 = 24 8/9

1/8 x 10 2/3 = 1 1/3

10 2/3 x 3/5 = 6 2/5.

Hope this helps!

Solve x^2 – 12x + 36 = 90 for x

Gnesinka [82]

X^2-12x+36=90
x^2-12x-64=0
factor: (x-16)(x+4)=0
by the zero product theorem,
x-16=0 or x+4=0
=>
x=16 or x=-4
