Acompany charges $59.99 for cable tv installation and $49.99per month for basic cable service. write an algebra expression to represent the total cost of m months of basic cable service, including installation

49.99m + 59.99

Step-by-step explanation:

$59.99 is a one time fee and $49.99 is per month

49.99m + 59.99

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 5 hours i think idk i'm not that good at math.can you me with my questions i need asap.
