The answer is B.
(the equation to solve this with is: a^2 + b^2 = c^2)
Answer:
If the line RS has been rotated 90 degrees, then VU will be perpendicular to RS and the two slopes must be opposite and reciprocal, i.e. product of the two slopes will equal -1.
As a verification, we find the locations of V and U from rotations of R & S.
(actually, the triangle had been rotated -90°, 90 ° clockwise)
Step-by-step explanation:
Slope RS, m1:
Slope VU, m2
Hence m1*m2=1*-1=-1, meaning that m1 and m2 are opposite (in sign) and are reciprocal to each other, as expected
F(180) = x/30
= 180/30 = 6 gallons of gas is needed
Answer: 8
Step-by-step explanation:
8x - 2y = -8
-5x + 2y = -1
3x = -9
x = -3
