What is the solutions of the equation 2 (x+2) ^2-4=28

JulsSmile [24]

Answer:

x = 2 x = -6

Step-by-step explanation:

2 (x+2) ^2-4=28

Add 4 to each side

2 (x+2) ^2-4+4=28+4

2 (x+2) ^2= 32

Divide by 2

2/2 (x+2) ^2=32/2

(x+2)^2 = 16

Take the square root of each side

sqrt((x+2)^2) =±sqrt( 16)

x+2 = ±4

Subtract 2 from each side

x+2-2 = -2±4

x = -2±4

x = -2+4 and x = -2-4

x = 2 x = -6

8 Graph the equation y = –20x + 500.

Tomtit [17]

Answer:

Step-by-step explanation:

you have to plot the y-intercept first so since we know that the y-intercept is 500 from the y=mx+b format, you have to plug in (0,500). Then, we use the slope or the m provided in the equation with is -20. This means you have to go down 20, and right 1 since it is -20/1 or 20 down and 1 run. then you just connect the dots to finish your line.
