The graph shows the solution to which inequality?

Slope (m) =

ΔY

ΔX

=

4

3

=1.3333333333333

θ =

arctan(ΔY) + 180°

ΔX

=233.13010235416°

ΔX = -3 – 3 = -6

ΔY = -6 – 2 = -8

Distance (d) = √ΔX2 + ΔY2 = √100 = 10

Equation of the line:

y =  4/3x – 2

When x=0, y = -2

When y=0, x = 1.5

D.

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
