Answer:

Step-by-step explanation:

Calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (- 1, 2) and (x₂, y₂ ) = (5, 8 )

m = $\frac{8-2}{5+1}$ = $\frac{6}{6}$ = 1 → A

Given the function f(x)= 2|x+6|-4, for what values of x is f(x)=6?

Paraphin [41]

Answer:

x = -1 or x = -11

Step-by-step explanation:

f(x)= 2|x+6|-4

2|x+6|-4 = 6

2|x+6| = 6+4

2|x+6|=10

|x+6| = 10/2

|x+6| = 5

x+6 = ±5

x = ±5 - 6

x = -1 or x = -11

Answer:

$15\sqrt{x}$

Step-by-step explanation:

$\sqrt{(25*9)x}$

Start by "taking out" the perfect squares. 25 and 9 are perfect squares (and pretty common ones).

The square root of 25 is 5 and the square root of 9 is 3. Therefore you can take out a 5 and 3 from the radical. Multiply the numbers you take out together.

5 * 3 = 15

The number outside of the radical sign will be a 15, and x is left over inside the radical. The final answer is $15\sqrt{x}$ .
