Abdul received a $50,50 gift card for a photo center. He used it to buy prints that cost 8 cents each. The remaining balance, B (In dollars), on the card after buying x prints is given by the following function.
B(x) = 50.50 -0.08x
What is the remaining balance on the card if Abdul bought 30 prints?

The remaining balance on the card is $48.1

Step-by-step explanation:

i.e 50.50 -0.08(30) = 48.1

true statements:

a) x + y = y + x   ⇒ commutative property of addition

b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication

d) (x + y) + z = x + (y + z) ⇒ associative property of addition

false statements:

c) x - y = y - x   should be: x - y = - y + x

e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)

step-by-step explanation:

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option
