A :-) 4 ( x - 7 )^2 - 48 = 12
= 4 ( x^2 - 49 ) - 48 = 12
= 4x^2 - 196 - 48 = 12
= 4x^2 - 244 = 12
= 4x^2 = 12 + 244
= 4x^2 = 256
= x^2 = 256 by 4
= x^2 = 64
= x = _/64
= x = 8

.:. x = 8

Solve (x - 5)2 = 3.O A. x = -51 1/3O B. x = 3 15O C. x = 5+:13O D. x = 8 and x = -2
Virty [35]

In order to solve the given expression follow these steps:

1. Take the square roots on both sides in order to get rid of the power on the left side:

√(x-5)² = ±√3

x - 5 = ±√3

2. add 5 on both sides:

x-5 + 5 = 5 ±√3

x = 5 ±√3

Then, the solution is x = 5 ±√3

How do you find the slope on a graph
podryga [215]
Remember that the slope of a line never changes, so you can choose whatever 2 points you want and you will always get the same slope. Calculate the rise and run (You can draw it on the graph if it helps). Theslope is 2/4, which , of course, you can simplify to ½.
