Answer:
x=-3
Step-by-step explanation:
we know that
The slope of a vertical line is undefined
The formula to calculate the slope between two points is equal to
we have
A(x+14, 5) and B(2−3x, 8)
substitute
so
If the slope is undefined
then
The denominator must be equal to zero
solve for x
So the Rational Zeros Theorem states that <u>the potential zeros are ± P/Q, with P = factors of the constant and Q = factors of the leading coefficient.</u>
In this case, the constant is -3 and the leading coefficient is 2.
- P = 1,3
- Q = 1,2
With P and Q established, divide them all as such:
<u>In short, your potential zeros are ± 1/2, ± 3/2, ± 1, and ± 2.</u>
