Your answer to 2/3x-4= -2 would be
x=3, or letter D
Answer:
45 degrees
Step-by-step explanation:
you would do 20-(-25) then that turns to 20+25 and you get 45
Answer:
slope = -1
Step-by-step explanation:
parallel lines have the same slope,
y = -x – 4
=> y = -1(x) -4
↑ slope
y = mx + b
↑ slope
Answer:
x = 55
Step-by-step explanation:
A triangle equals 180 degrees, b will be used to find the missing angle.
21 + 34 + b = 180
55 + b = 180
subtract 55 from both sides
b = 125
A straight line is 180 degrees and the b, the missing angle, and x are supplementary angles so
125 + x = 180
x = 55
