Answer:
c. x = 0
Step-by-step explanation:
2(x-3)+9=3(x+1)+x
⇔
2x - 6 + 9 = 3x + 3 + x
⇔
2x + 3 = 4x + 3
⇔
2x = 4x
⇔
4x - 2x = 0
⇔
2x = 0
⇔
x = 0
Answer:
(5, 4) is correct.
First comes x, which is horizontal on the graph
Then comes y, which is vertical.
The path of the ball is the diagonal of the rectangle.
You can use the Pythagorean theorem.
a^2 + b^2 = c^2
64^2 + 48^2 = c^2
4096 + 2304 = c^3
6400 = c^2
c = 80
Answer: 80 meters
Answer:
99
Step-by-step explanation:
the supplementary angle is just the two angles that equal 180 degrees.
x+81=180
-81=-81
x=99
simple check
81+99=180
