A utility company charges $0.14 per kilowatt-hour for energy a customer uses. They give a credit of $0.035 for every kilowatt-hour of electricity a customer with a solar panel generates that they don't use themselves. A customer has a charge of $95.14 and a credit of $6.02 on this month's bill.

a) What is the amount due this month?

b) How many kilowatt-hours did they use?

c) How many kilowatt-hours did they generate that they didn't use themselves?

3. parallelogram

step-by-step explanation:

we turn each of our sides into direction vectors

ab=b-a=(3 - 7, 1 - 0) = (-4, 1)

bc=c-b=(1,6)

cd=d-c=(4,-1)

da=a-d=(-1,-6)

we see how the opposite sides have negated direction vectors; this is characteristic of a parallelogram.   we have congruent sides ab=cd and bc=da with unequal lengths because 1^2+6^2 is different from (-4)^2+1^2.   so it's not a square or a rhombus.  

we check the dot product of direction vectors of adjacent sides.   we have

ab dot bc = -4(1) + 1(6) = 2

that's not zero so the sides are not perpendicular.   we've ruled out rectangle.

the direction vectors indicate two pairs of congruent parallel sides, so we choose parallelogram over trapezoid.

the answer to the expression is 83

uhhh idk u yolo?

step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3
