Dan, age 15, also wants to purchase "Run Fast, Jump High" sneakers for $100. He decides to wash cars in the neighborhood during the summer. He has five steady customers who want him to wash their cars every week for the eight weeks. He charges seven dollars per car. He's decided to spend his first two weeks salary on movies, candy, and bowling with his friends. He tries to save half of his earnings for the rest of the weeks but only saves ten dollars each week. Will he have enough to buy his sneakers? Why or why not?

No, because that means each week he will earn 35 and he uses all but 10. Then he contines that for 8 weeks to get 80$ dollars not 100$ so he does not have enough,.

Step-by-step explanation:

b i think

step-by-step explanation:

not really sure

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
