Joan needed $100 to buy a graphing calculator for her math class. Her neighbor will
pay her $5 per hour to babysit and her father gave her $10 for mowing the lawn.
Which inequality represents the minimum amount of hours she will need to babysit in
order for her to buy her calculator?
5x - 100 2 10
5x + 10 > 100
5x + 10 2 100
10x + 5 = 100

5x + 10 2 100

Step-by-step explanation:

its the minimum

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?
