Answer:
x= 1/31
Step-by-step explanation:
it mental math
ANSWER
x = 4
EXPLANATION
1) 1+4x = 13+x
2) 1+3x = 13
3) 13 - 1 = 12
4) 3x = 12 (Solve for x by dividing 3 on both sides)
5) x = 4
Answer:
b perpendicular
Step-by-step explanation:
all that is needed to do is the Y2 - y1 / X2 - X1 formula and then compare the two slopes making sure they are inverse opposites
Line 1) -7 -8 / -3 -2 X= 3X
Line 2) -3 - 0 / 12 - 3 X = -1 / 3X
Because they are inverse opposites of each other they are perpendicular had they had the exact same slopes they would have been parallels.
