Answer:
17
Step-by-step explanation:
angle one and angle three are equal to each other
so if you set the equations equal to each other
(4x+2)=( 5x-15)
move the 4x the right by subtracting it giving you 1x
then add 15 to 2 giving you 17
17=1x
Answer:
- 7/4
Step-by-step explanation:
1) (y2 - y1)/(x2 - x1)
2) pick two points, mine were (1,-3) and (-3,4)
3) Substitute the values (4+3)/(-3-1)
4) Solve and no matter what points you’ll get -7/4
