Answer:
98.57
Step-by-step explanation:
3.5% over 100% X 102=3.43
102-3.43= 98.57
How the quadratic formula works:
For any quadratic equation ax² + bx + c = 0, the solution is

.
In the case of our equation 7x² - x = 7, first we need to subtract 7 from each side so that we have 0 on the right.
7x² - x - 7 = 0
Identify the values of a, b, and c.
a = 7, b = -1, and c = -7.
Plug these into our quadratic formula and solve.

There are two values for x: (1+√197)/14 and (1-√197)/14.
The approximate values for these are 1.073976 and -0.931119.
from least to greatest: 0.85, 8/9 (0.88 as a decimal), 0.93
By intuition, the function of y with respect to x will be:
y = 4x
You can prove this by substitute in each pair of values of x and y
So the constant of relationship is 4
