Answer:
<u><em>h(x+2)= x² +5</em></u>
Step-by-step explanation:
h(x)= x² +5 -2x
h(x+2)= (x+2)² +5 - 2(x+2)
h(x+2)= x² +4x+4+5-4x-4
h(x+2)= x² +5
Answer:
x=7
Step-by-step explanation:
Starting with (x-2)² = 25
First, square root both sides to get rid of the square on the left. You'll get:
x-2 = 5
Add 2 to both sides to get x alone. You'll get:
x=7
Check your answer by filling in 7 for x:
(7-2)² = 25
(5)² = 25
25 = 25
When you write the equation of a circle in the form
![(x-x_0)^2+(y-y_0)^2=r^2](https://tex.z-dn.net/?f=%28x-x_0%29%5E2%2B%28y-y_0%29%5E2%3Dr%5E2)
Then the center of the circle has coordinates
and the radius is ![r](https://tex.z-dn.net/?f=r)
So, in your case, the center of the circle is ![(3,7)](https://tex.z-dn.net/?f=%283%2C7%29)
Answer: (-3,7)
