Ruby wants to start her own business taking photographs. she already has her own camera, but needs to purchase lights, a photo printer, and photo paper. if the cost of the photo printer is $251.99, the cost of lighting is $150.00, and the cost for 100 sheets of photo paper is $30.98, determine how much of her savings will be used to start her company, given that she has $840.32 in savings. a. $432.97 b. $840.32 c. $432.62 d. $407.35

Ruby wants to start her own business taking photographs. She has to purchase

In total, she will use

$251.99 + $150.00 + $30.98 = $432.97.

If she has $840.32 in savings, then

$840.32 - $432.97 = $407.35 will remain.

she will use $432.97 - correct answer A

triangle abc is reflected on the line x=-6.5 then reflected again on the x axis

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
