Write the linear equation in slope intercept form

The slope intercept form

Step-by-step explanation:

Slope intercept form is y=mx+b, where M is Slope and B is the y-intercept. We can use this form of a linear equation to draw the graph of that equation on the x-y coordinate plane. Slope intercept form is Y=MX+B Where M is The SLOPE and B is the Y-INTERCEPT.

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
