Calculate Matthew's Income: Calculate Matthew's Expenses:
$10.75 an hour x 18 hours = $ 193.50 a week
Rent = $450.00
$193.50 x 2 weeks = $387.00 per paycheck
Groceries = $200.00
$387.00 - 10% = $348.30
Phone, Internet and Cable = $175.00
$348.30 x 2 paychecks a month = $696.60 a month
Monthly Income =
Monthly Expenses =

chase is right because he already been to the swings and he know how far it will be to get there

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
