HELP ME OUT PLS!!! 1) Which algebraic rule describes the transformation?

A) (x, y) → (-x, y)

B) (x, y) → (x, -y)

C) (x, y) → (-x, -y)

D) (x, y) → (-y, -x)

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 formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:

d is the only accurate one
