Answer: y2/4 - x2/5
Step-by-step explanation:
2 * x/100 = 8
x/100 = 4
x = 400
400%
Answer:
Step-by-step explanation:
Y = kx is the direct variation equation. First find k, the could variation. 16 = k * 20. Divide both sides by 20. 16/20 = k 4/5 = k. The direct variation is "y=kx" . As "x" increases the value of "y" increases.
The slope of that is (2, 3.5)
-3x^3 - 4x
x = -1
-3(-1)^3 - 4(-1)
(-1)^3 = (-1) x (-1) x (-1) = -1
-3 x -1 = 3
-4 x -1 = 4
3 - 4 = -1
-1 is your answer
hope this helps
