you can only afford basic as both other options are over $100

Step-by-step explanation:

standard = 964 - 50 = 914 left

914/8 = 114.25 per month

formula: 8m + 50 = 964

deluxe = 1940-50 = 1890 left

1890/18 = 105 per month

formula: 18m + 50 = 1940

need more information

step-by-step explanation:

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
