A reflection is applied to triangle ABC according to the rule (x, y) - (x, y). Which of the following will describe the effect of the reflection? Select one:
O C will stay as the bottom vertex.
O A' will stay as the top vertex.
O C will now be the top vertex.
O B' will be the bottom vertex.​

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

the answer is -6

step-by-step explanation:

the answer is -6 because its next to the variable m

the answer to 1/4x+5/3x-4=2-1/12x is x=3

hope this if needed hmu
