Which equation, when graphed, has x-intercepts at (−1, 0) and (−5, 0) and a y-intercept at (0, −30)? f(x) = −6(x + 1)(x + 5) f(x) = −6(x − 1)(x − 5) f(x) = −5(x + 1)(x + 5) f(x) = −5(x − 1)(x − 5)

the first question mark is 6 and the second question mark is 26 (the square root)

step-by-step explanation:

on your paper it doesn't say the answer but the the answer is altitude

step-by-step explanation:

boxplot e is the answer

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
