<h3>What is a Quadratic Function ?</h3>
A quadratic function is given by ax² +bx+c = f(x)
The given quadratic function is
f(x) = 6x² +12x - 7
The zeroes of the function will be given by
f(0) = 0
6x² +12x - 7 = 0
The zeroes are given by
here
a = 6
b = 12
c = -7
Therefore the zeroes of the function will be
Therefore these are the two zeroes of the function.

Solution:
<u>Simplify the equation and solve for r.</u>
- r/16 + 6 = 7
- => r/16 = 7 - 6
- => r/16 = 1
- => r = 16
The value of r is 16.
<u>Check:</u>
- r/16 + 6 = 7
- => 16/16 + 6 = 7
- => 1 + 6 = 7
- => 7 = 7 (Proved correct)

Step-by-step explanation:
She earns $8/hour
And she works weekend only
He is saving his earning to go for ski and it cost $190
For him to save $190, let know the hours he is going to work
