For what value of x is the rational expression below equal to zero?
x - 9
(х – 4 )(х + 4)
a. 9
b.-4
c.4
d.-9

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.

if i put something wrong your not gonna like it so rather not say nothing.
