What is the slope in y + 4 = -2(x - 9)?

is y=−2x+14

Step-by-step explanation:

because yo.multipli

y- y1 =m(x -x1)

comparing these; -y1= 4;y1 = -4

m= -2 ;x1 = 9

The slope is -2

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

it would take 7/10 of an hour too fill the pool.
