Answer:
22a + 12b
Step-by-step explanation:
First, you should combine like terms. Like terms are when numbers have the same variable, such as the variable 'a'.
26a and -4a both have 'a' as their variable. To combine them, add -4a to 26a. You should get 22a as your final result.
The other two numbers in this equation that share a common variable are 2b and 10b. To combine these, all you have to do is add them together. After adding these two, you should get 12b.
After combining all like terms, there is none left, meaning you can't combine 22a and 12b since they don't share the same variable.
Answer:
Answer C:
Step-by-step explanation:
Notice that all the functions look like x plus a constant in the numerator, and x minus the same constant in the denominator.
So we can do a general analysis finding the inverse of a function of the form:
and finding which value of "a" will make
To find the inverse we need to solve for "x" in the equivalent equation:
Then, we see that if , then the expression for
Then the function that verifies this condition is:
Answer:
t ≤ -135
Step-by-step explanation:
multiply each side by 5 which then cancels out the 5 in the fraction then turns -27 into -135. Since we multiplied negatives we flipped the sign.
Virgil has 1/6 of the original cake, which he wants to divide into 4 parts. Thus:
1/6 / 4
= 1/6 x 1/4
= 1/24
Each person will receive 1/24 of the original cake.
