The answer is B. In 10 hours, the phone would completely lose its charge.
Y=-10(10)+100=-100+100=0
ABC is a isosceles triangle
AC = BC
so
<A = <B
2x - 20 = x + 8. solve for x
subtract x to both sides
2x - 20 - x = x + 8 - x
x - 20 = 8
add 20 to both sides
x - 20 + 20 = 8 + 20
simplify
x = 28
<A = <B = 28 + 8 = 36
<C = 180 - 2(36)
<C = 180 - 72
<C = 108
Answer
B. 108 degrees
First you divide the total with the amount of hours you worked
45/5 = 9
9 is the amount of money you earn per hour
so your answer is $9 per hour
hope this helps
