Answer:3 hours
Step-by-step explanation:8-5=3, 3-5=-2, -2-5=-7
Answer:
y = -½x + 4
Step-by-step explanation:
1 = -½[6] + b
-3
4 = b
2y + x = 4 →2y = -x + 4 >> y = -½x + 2 [parallel to the above equation]
Parallel lines have SIMILAR <em>RATE</em><em> </em><em>OF</em><em> </em><em>CHANGES</em><em> </em>[<em>SLOPES</em>].
I am joyous to assist you anytime.
**I have a video that explains how to find the y-intercept, Perpendicular Equations, and Parallel Equations. I encourage you to watch the video to gain alot more knowledge from it, so you can better understand the concept. It is the second longest.
since the triangles are similar
angle DEC = 60 degrees
3 angles inside a triangle equal 180 degrees
BAC = DCE = 64
CBA = EDC = 56
DEC = 180 -56 -64 = 60 degrees
used angle-angle theorem
Answer:
8 (3x - 1) = 2 (9 – 7x)
24x - 8 = 18 - 14x
24x + 14x - 8 = 18 -14x + 14x
38x - 8 = 18
38x - 8 + 8 = 18 + 8
38x = 26
38x / 38 = 26 / 38
x = 13/19
Step-by-step explanation:
1. distribute both sides
2. add 14x to both sides
3. add 8 to both sides
4. divide both sides by 38 to get x
