Answer:

Step-by-step explanation:
The general direct variation equation is
y = kx
Plug in x = 4 and y = 6 and solve for k.
6 = k * 4
4k = 6
k = 6/4 = 3/2

Answer:
The only difference is: If you multiply or divide both sides of an equation by the same negative number, the equation remains the same, but If you multiply or divide both sides of an inequality by the same negative number, the inequality reverses.
Answer:
a^2 = c^2 - b^2
to get A though you need to take the square root.
Step-by-step explanation:
you need to rearrange the formula to get a by itself.
c^2 = a^2 + b^2
a^2 = c^2 - b^2
to get A though you need to take the square root.
