Which inequality describes the points shown on this number line

x 3 OR x > 10

Step-by-step explanation:

We see that the dot on 3 is filled in, so it has to be either greater than or equal to or less than or equal to.

10 is NOT filled in, so it has to be either less than or greater than.

Since the values are decreasing from 3, x is less than or equal to 3

and since the values are increasing from 10, x is greater than 10.

Thus, the answer is x 3 OR x > 10

step-by-step explanation:

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
