Answer:
520<400+15x
15x>120
15x+400>520
Explanation:
Pay of Dan's car wash attendant job =$400 per week
The amount he earns per hour walking dogs = $15
Let the number of hours spent walking dogs in a week = x
Therefore, total earning for walking dogs =$15x
Since he wants to earn more than $520, we have that:
We can rewrite this as:
If we collect like terms, we have:
So the inequalities are:
0. 520<400+15x
,
1. 15x>120
,
2. 15x+400>520
8 x 64=
8 x 32 x 2
64 x 4 x 2
128 x 2 x 2
=512

Good luck!
Let n be the number 18=60% of n
18=0.6n
18/0.6=n
30=n
Finding the intercepts is a very straight-forward process. First set y = 0 and solve the equation for x. That is your y-intercept! Then go back to the original equation and set x = 0 and solve for y. That is your x-intercept! For a linear equation like this there is only one x-intercept. For any "function" y(x) there can by definition be only one y-intercept.
