To answer this question, we start by equating the denominators of each option to 0; then, solve for x
(a):

This gives

Set the denominator to 0

Solve for x

Factorize:


This implies that:

From above, one of the values of x is 7.
This implies that x = 7 is an excluded value for this quotient.
<em>Other options do not need to be checked, since there is only one answer.</em>
It’s c because slope usually has to deal with numbers
Answer:
The length of a pen.
Step-by-step explanation:
A length of a pen is around three inches and is reasonable but all of the others are way too big and can be measured in feet or miles.
To solve Systems of Equations you can use graphing, substitution, or by adding, subtraction, multiplying, or division methods. One solution is consistent and dependent. No solution is inconsistent. Infinitely many solutions is consistent and dependent.
