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
Answer:
Do not qualify
Step-by-step explanation:
Yearly income = $58000
Monthly income = = $4833.33
Median annual income = $47778
Monthly expenses = $4600
Income < Median Income ? 58000 < 47778 -> No
x = (Monthly income - expenses) * 60
= (4833.33 - 4600) * 60
= 233.33 * 60
= 13999.8
x < 10000 ? 13999.8 < 10000 -> No
So, Do not qualify
You first have to turn 2x + 4y = -8 into y = mx + b before graphing. To do this, you subtract 2x from the left side of the equation because inverse operations. This will bring 2x to the right side. Now, you will have 4 = -2x + 8. However, you cannot have a number with y. Therefore, you must divide -8 and 2 by 4. You will get y = -1/2 x + 2 as your equation.
To graph -1/2x + 2, you must remember rise/run. Since it is NEGATIVE -1/2, your slope will go downwards (1 down, 2 across) starting from y = 2.
