It is (7x)
^(2/3). If we look at our exponent laws (SEE ATTACHMENT), we can see that we can express our equation as so.
Answer:inversely proportional
Step-by-step explanation:
As the value of x increase the value of y decrease
We are given the following relation:
y = 4.302 x – 3.293
To solve for the mean value of y when x = 20, what we have
to do is to find for the value of y at x = 20 and the value of y at x = 0. Then
we get the average of the two values.
when x = 0
y(0) = 4.302 (0) – 3.293
y(0) = - 3.293
when x = 20
y(20) = 4.302 (20) – 3.293
y(20) = 82.747
The mean value would be:
mean y = [y(20) + y(0)] / [20 + 0]
mean y = [82.747 + (-3.293)] / 20
<span>mean y = 3.9727 = 3.97</span>
Answer:40
Step-by-step explanation:
100+10+10=3x
3x=120
Divide both sides by 3
X=40
