(0,4) (0,-2) (-2,0)
for the reflection over the x-axis, all the y values go to their opposite (0,-4) (0,2) (2,0)
then at the rotation it goes (-x,-y) and becomes (0,4) (0,-2) (-2,0)
Elevation above sea level = 2x+50
rock climbers minute of climbing = x
2x + x + 50
3x + 50
Answer:
substitution
Step-by-step explanation:
We assume the two equations are ...
You are given an expression for x. Using that in the second equation will result in an immediate solution for y.
... 2(2y+4) -3y = 11 . . . . . substituting 2y+4 for x
.. y +8 = 11
... y = 3
... x = 2·3 +4 = 10
The solution is (x, y) = (10, 3)
Answer:
The easiest way would be to try to solve for x
