Answer: There is one valid solution to the equation 5x + 8 - 7x = -4x + 1, x = -3.5.
Step-by-step explanation:
The best fit line would show a slope of 1 (if you count the rise/run in that graph, it’s 1/1).
Answer:
38-15c-4
Step-by-step explanation:
38-x=12c+4+3c
38-x=15c+4
x=38-15c-4
Answers: 11-20
Step-by-step explanation: Step 1. Flip the equation Step 2. Add the number to both sides Step 3. Divide both sides by the number to get your answer.

Answer:
possible solutions (2,11) (3,10)
Step-by-step explanation:
Variable Definitions:
x=the number of hours babysitting
y=the number of hours walking dogs
“no more than 14 hours"→14 or fewer hours
Therefore the total number of hours worked in both jobs, x+y, must be less than or equal to 14
x+y≤14
“no less than $120"→$120 or more
Aubrey makes $8 per hour babysitting, so in x hours she will make 8x dollars. Aubrey makes $10 per hour walking dogs, so in y hours she will make 10y dollars. The total amount earned 8x+10y must be greater than or equal to $120:
8x+10y≥120
Solve each inequality for y:
x+y≤14
y≤14−x
8x+10y≥120
10y≥120−8x
y≥ -4/5x+12
Graph y≤14−x by shading down and graph y≥-4/5x+12 by shading up
