8: slope is 1/2 and y intercept is 0
9: slope is 7/4 and y-intercept is 0
Answer:
-2x
Step-by-step explanation:
The expression itself is -2x. We subtract the coefficients 7 and 9 to get -2.
Using pythagorean theorem:
She will have $500 in 5 days because when she takes out the 20 every week she will have had $100 so to make $500 she will have to have made 5 $100
It will take him 28 weeks. If he already has $60 of $200 saved, you would do 200 - 60. That would give you 140. To find out how long it would take him to make $140, you would have to do 140 divided by 5 to get the number of weeks.
