Write an algebraic expression to model the situation at your after school job you earn $7.75 per hour and are expected to pay a one time fee of $17 for the uniform. if you work x hours per week how much will you make during the first week?

Algebraic expression is 7.75 x - 17

Step-by-step explanation:

you earn $7.75 per hour and are expected to pay a one time fee of $17 for the uniform.

LEt x be the number of hours you work

for 1 hour of work , you earn = 7.75

For x hours of work , you ear = 7.75 x

one time fee = $17

So we subtract the fee for the uniform from the first week earning

Expression becomes

7.75 x - 17

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

1 + (6 / x - 1)

step-by-step explanation:

divide using polynomial division.
