Gallons! gallons!! GALLONS!!! GALLONSSS!!!! hahaha. They're all the same so C. gallons. :).....xD
Answer:
C. –2x – 10 = –2(x + 5)
Step-by-step explanation:
Clearer choices:
2x + 10 = –2(x – 5)
–2(x + 5) = 2x – 10
–2x – 10 = –2(x + 5)
–2(x – 5) = –2x – 10
All choices have either:
–2(x – 5) for A and D
or –2(x + 5) for B and C
Simplify these expressions by <u>expanding</u> with the distributive property. Multiply the outside term "–2" with each term inside the brackets.
–2(x – 5)
= (–2*x) – (–2*5) Multiply each term by the coefficient
= –2x – (–10) Simplify the double negative to a positive
= –2x + 10 Expanded expression
This is not the same answer in A and D. They are not correct.
–2(x + 5)
= (–2*x) + (–2*5) Multiply each term by the coefficient
= –2x + (–10) Adding a negative is the same as subtraction
= –2x – 10 Expanded expression
This is the same answer for <u>option C</u>.
Therefore "C" is the answer.
Answer:
Step-by-step explanation:
a ratio is comparing to things to gather and than simplifying to the smallest numbers
First let P(x) = g(x)/f(x) = x^2 - 9 / 2 - x^0.5
The domain of the nominator is any value
The domain of the denominator is
Zeros of the denominator
2-x^0.5 = 0
-x^0.5 = -2
x^0.5 = 2
x = 4
domain of x^0.5 is x >= 0
(0,4) and (4, inf)
