Answer:
90.
Step-by-step explanation:
7m - 3 = 53
m would be 8 because 56 - 3 = 53.
11m + 2 equals 90 because 11 times 8 (8 is m) is 88, which added by two is 90.
Answer:
(0,5)
Step-by-step explanation:
Perpendicular lines have slopes which are negative reciprocals of each other. The slope of the line y=1/2x + 6 is 1/2. The slope perpendicular to it is -2.
Using m=-2, substitute it and (4,-3) into the point slope form and simplify to find the y-intercept.

The equation is now in slope intercept form y=mx+b and b is the y-intercept. The y-intercept of y=-2x+5 is (0,5).
edit: i think i got it wrong the first time. but :> is just a cute lil smiley face!
Answer:
according to me the answer is 200
Answer:
-32 / -4 = 8
x = 8
Step-by-step explanation:
8(-4x + 1) = 4(10 - 9x)
-32x + 8 = 40 - 36x
+32x +32x
8 = 40 - 4x
-40 -40
-32 = -4x

-4
