Answer:
slope perpendicular= -1
Step-by-step explanation:
3x-3y=-63
-3y=-3x-63 divide both sides by -3
y=1x+21
Perpendicular lines have slopes that are the opposite of the reciprocal of each other
With $17.50 she can get 11 2/3 gallons. 11 (she just got) + 8 (that she had) = 19 gallons. 19 x 27 MPG = 513 Miles.
27 divided by 3 = 9 (9 is a third of the MPG) 9 x 2 (since it was 2 thirds that were left) = 18
In total she can drive 531 miles.
<u>Answer-</u>
<em>The values of x and y are </em><em>13</em><em> and </em><em>24</em><em>, respectively.</em>
<u>Solution-</u>
From the attachment, l and m are parallel lines and
---------------------1
As, when a traversal line intersects two parallel lines, same-side interior angles are supplementary, or they add up to 180 degrees.
---------------------2
As, an exterior angle is equal to the sum of the opposite interior angles.
Adding equation 1 and 2, we get,
Putting the value of x in equation 1, we get
<span>well first off, you take 1350/9=150
then you add it all together 1350+150=1500
then your full answer would be $15 was the original price
