Answer:
the first one
the third one
and the forth one
Step-by-step explanation:
they all add up to the same amount
The 3 inside angles of a triangle need to equal 180 degrees.
The angle below the 100 degrees would be 180-100 = 80 degrees.
Now you have 80 and 70, which equals 150 degrees.
Angle X = 180 -150 = 30 degrees
The first expression goes into m - 1
the second expression is m - 2 / m
and the last expression goes m - 2 / m - 1
Y = 1/2x + 6
slope here is 1/2. A parallel line will have the same slope.
y = mx + b
slope(m) = 1/2
(0,-2)...x = 0 and y = -2
now sub and find b, the y int
-2 = 1/2(0) + b
-2 = b
so ur parallel equation is : y = 1/2x - 2
Answer:
y=10
