Pls i am completely stuck! 50 points! mrs. bull spilled coffee on her computer during the first week of school! the total cost after tax to repair it is represented by 0.09(75h) + 75h, where h represents the number of hours it takes to repair her computer. what part of the expression represents the amount of tax mrs. bull has to pay? i need the total tax that she paid, and explain it! you!

0.09(75h) is the part of the expression that represents the amount of tax Mrs.Bull has to pay. 75h (h representing the number of hours it will take to repair the laptop) is the amount before tax, so 0.09 and 75h multiplied will equal the total of tax.

Hope this helps you

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?
