83x + P = 83x + Q <em>subtract 83x from both sides</em>
P = Q
The equation has no solution for P different Q (P ≠ Q).
The formula for x in terms of w is x = 3w² and the formula for y in terms of x is y = (1/112)x³
<h3>Variation</h3>
x = k × w²
w = 4, x = 48
48 = k × 4²
48 = k × 16
48 = 16k
k = 48/16
k = 3
So,
x = k × w²
x = 3 × w²
x = 3w²
y = k/x³
x = 2, y = 14
14 = k / 2³
14 × 2³ = k
14 × 8 = k
112 = k
So,
y = k/x³
y = 112/x³
y = (1/112)x³

Answer:
y = mx + b would be your starting equation. You need two coordinates for to find your slope (mx). You multiple your slope (m) with your x-coordinate given (x). Then after multiplying, you subtract that with y to find your b. Thus, the answer. You'll want to ask yoru teacher for more help if you don't get it. :)

Answer:
4%
Step-by-step explanation:
1) Subtract the base price from the final price. 40.56 - 39 = 1.56.
2) Divide the tax by the base price to determine the decimal version of the percentage. 1.56 / 39 = 0.04.
3) Multiply this by 100 to turn it into the normal percentage. 0.04 × 100 = 4, so the answer is 4%.
