Answer:

x = -3±sqrt( 5)

Step-by-step explanation:

(x + 3)^2-5=0

Add 5 to each side

(x + 3)^2-5+5=0+5

(x + 3)^2 = 5

Take the square root of each side

sqrt((x + 3)^2 )=±sqrt( 5)

x+3 = ±sqrt( 5)

Subtract 3 from each side

x+3-3 = -3±sqrt( 5)

x = -3±sqrt( 5)

What are the slope, m, and y-intercept, (0,b), of the line described by the equation 3x+6=12

alina1380 [7]

Answer:

slope=3,y-intercept=6

Step-by-step explanation:

Slope is the rate of change so It is an independent variable and has an x at the end

The y-intercept is the initial value which is technically the start off and the number 6 seems to be a dependent variable.
