Answer:

Step-by-step explanation:

Alright, lets get started.

The given equation is :

2(5x+2)^2=48

If we divide it from 2 in both sides

\frac{2(5x+2)^2}{2}=\frac{48}{2}

(5x+2)^2=24

Taking square root on both sides

(5x+2)=±24

(5x+2)=±2√6

Subtracting 2 in both sides

5x=±2√6-2

Dividing 5 in both sides

x=\frac{2\sqrt{6}-2 }{5} or x=\frac{-2\sqrt{6}-2}{5}  :  Answer

Hope it will help :)

Find an equation of the line passing through the pair of points. Write the equation in slope-intercept form.
muminat

Answer:

y=10-x

Step-by-step explanation:

1. Find the slope of the equation using the formula (change in y/change in x)

(3-7)/(7-3)=-4/4=-1

2. Plug in the slope and one of the coordinate points to the slope-intercept form to find the y-intercept.

slope-intercept form: y=mx+b

7=-3+b

b=10

3. Put the slope-intercept form of the equation together.

y=10-x
