9. You have worked all summer long and saved $1240. You want to buy a car that costs $5400. How much
money, m, do you need before you can buy the car?
10.
at y
you

Step-by-step explanation:

We have to subtract the amount of money that you have earned by the amount of money that the car costs.

$5400-$1240 is $4160

So you need $4160 more money to buy the car

(Good luck getting that much money XD)

Hope this helps!

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph

45.36 feet per second

step-by-step explanation:

tyrone travels 30 miles in 58.2 minutes.  

1 mile = 5280 feet; this means he travels

30(5280) = 158400 feet in 58.2 minutes.

1 minute = 60 seconds; this means he travels 158400 feet in

58.2(60) = 3492 seconds.

this gives us the unit rate of

158400/3492 = 45.36 feet per second.
