Answer:
0.25 (inches?)
Step-by-step explanation:
the equation is:
y=mx+b
y is the length of her hair, the dependent variable, the outcome
m is the slope, which is in this case the growth of her hair in a month
x is the independent variable, or the number of months
b is how long her hair is to start with, which is 12 in
we are looking for m, which is the growth of her hair per month, which is given as 0.25 inches, so that would be the answer
7 times 0.45 divided by 5 and you get 0.63

Answer:
Kevin is going to be able to have enough money for the concert the fastest
Philip needs at least 4 weeks
Kevin needs at least 3 weeks
Step-by-step explanation:
<u>Philip</u>
- $8.75/hour * 6 hours/weekend * 1 weekend/week = $52.5/week
Let's call x to the number of weeks Philip needs to reach $225.
52.5*x + 45 = 225
52.5*x = 225 - 45
x = 180/52.5
x = 3.43
He needs at least 4 weeks
<u>Kevin</u>
- 3 hours/day * $7.5/hour *3 days/week = $67.5/week
Let's call y to the number of weeks Kevin needs to reach $225.
67.5*y + 30 = 225
67.5*y = 225 - 30
y = 195/67.5
y = 2.9
He needs at least 3 weeks
