1. 12 mph, 24 miles
2. m=4, y=22
3.15/1, $1500
4. x=30 y=60, k cheaper, j cheaper
10*5+10*5*1 I think this is the right way
Since angles 3 and 4 form a linear pair, the sum of the measures of their angles must add up to 180.
We can define angle 3 as x, and angle 4 as (180-x).
x = 3 ( 180 - x ) + 4.
Solving for x, we get x=138. This is angle 3. Angle 4 is 180-138, so angle 4 is 42.
Answer:
slope is undefined
Step-by-step explanation:
x = 4 is the equation of a vertical line parallel to the y- axis.
The slope of a vertical line is undefined
