Answer:
Step-by-step explanation:
first remove the parentheses
then add the like terms
lastly reorder the terms
Both of your answers are correct. In the first equation, if you were to substitute 3 for x, because you have to do exponents first, you have 3^2, which is 9, and 9*6 =54. If you were to substitute -3 for x again you would have to do the exponents first which would be -3^2 which is 9, and 9*6 = 54.
For the second question, if I substitute 0.75 for t, I get -9 + 18 + 7. This is equal to 16, and therefore the answer would be D. Hope this helps! :D. Let me know if you have questions about my explanation, and feel free to post more questions.
Answer:
5.28 kg
Step-by-step explanation:
A farmer sells 8.8 kilograms of pears and apples at the farmer's market and 2/5 of this weight is pears.
Since a fraction is a part of a whole, 1, then, the fraction repressing the weight of the apples is:
1 - 2/5 = 3/5
Therefore, the weight of apples is/
3 / 5 * 8.8 = 5.28 kg
She sold 5.28kg of apples at the farmer's market.
Answer:
38x-22
Step-by-step explanation:
Answer: Choice D
============================================================
Explanation:
First we replace f(x) with y. This is because both y and f(x) are outputs of a function.
To find the inverse, we swap x and y and solve for y like so
Note: because the range of the original function is 
, this means the domain of the inverse is 
. The domain and range swap roles because of the swap of x and y.
As the graph shows below, the original and its inverse are symmetrical about the mirror line y = x. One curve is the mirror image of the other over this dashed line.
