Answer:
z = 0.9778x^2 / y.
Step-by-step explanation:
When z varies with the square of x the equation is z = kx^2 where k = a constant.
If it also varies inversely with y the equation is z = kx^2/y.
When z = 4.4 , x = 3 and y = 2 we have:-
4.4 = k * 3^2 / 2
Multiplying by 2:
8.8 = 9k
k = 8.8 / 9
= 0.9778.
So the required formula is z = 0.9778x^2 / y.
Answer:
x- intercept = 6
Step-by-step explanation:
to find the x- intercept, let y = 0 in the equation and solve for x
2x - 3y = 12
2x - 3(0) = 12
2x - 0 = 12
2x = 12 ( divide both sides by 2 )
x = 6 ← is the x- intercept
Answer:
No, its not equivalent
1/2 is equivalent though
Please mark as brainliest
Simple it is 1% because it is 1 out of 100 parts equaling 1%
Distance = Rate x time
Time = 4.5 hours
Rate = 70 miles per hour
Distance = 70 x 4.5 = 315 miles.
