Valerie is saving money for a new backpack. the one she wants costs $57.65. if she saves 7.25 a week, about how many weeks will it take her to have enough money for the backpack?

8 weeks

Step-by-step explanation:

Given Valerie want's to buy a backpack which costs $57.65

Also given that she saves $7.25 a week

Let the number of weeks she saves the money be x

For her to buy the backpack the following inequality should be satisfied

amount saved > cost of the item

The amount saved =

7.25x > 57.65

x > 7.95

Since x is an  integer we have x = 8

Therefore she has to save 8 weeks to buy the item

answer: finding the extract measurements and knowing the points

step-by-step explanation:

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
