First divide 2,280 by 60 so you know how many he must tell. Then, you know he already told two, so subtract two from the quotient and you should get 36.
So perp. is the slope flipped and changed signs because they have to equal to -1. so:
first you need to get it into slope intercept form:
4x - y = 16
-4x
-y = 16 - 4x
/-
y = 4x - 16
then flip and change the sign of the slope
y = -1/4x + b
add your coords
4 = -1/4(0) + b
4 = 0 + b
-0
4 = b
then make your new slope intercept form:
y = -1/4x + 4
answer:
y = -1/4x + 4
David > Chris
Chris < Annie
Annie = Sarah
Sarah < David
David is out since he is taller that Chris.
Anne is out since she is taller than Chris.
Sarah is out since Anne and Sarah are the same height.
Chris is the shortest, because he is shorter than Annie and Sarah, while Sarah and Annie are shorter than David, but Chris is shorter than Annie so Sarah applies too, Chris is shorter than Anne and Sarah.
Shortest ---> Tallest:
Chris, Anne, Sarah, David
Answer:
The value of x is 
Step-by-step explanation:
we have
------> equation A
In this problem we have
Substitute the value of g(x) in the equation A and solve for x
Divide by 
both sides
Adds 
both sides
Answer: 12.5%
Step-by-step explanation:
80x 12.5%=10
80+10=90
