Prove that quadrilateral Q(1, -2), D(13, 4), A(6, 8) and U(-2, 4) is a trapezoid.

Slope of AD Slope of QD Slope of UA Slope of QU

Which segments are parallel?

Which segments are perpendicular? Is the quadrilateral a trapezoid? Explain how you know.

right

step-by-step explanation:

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)

step-by-step explanation:

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
