A quick way to do this is by recalling the fact that
, so the largest value that
alone (for any real value of
) can take on is 1.
This means
, and so
.
So the maximum value of this function is 7.
12x² - 3.5y + 10y + 1.5x² + y Combine like terms
13.5x² + 7.5y
1.168 rounded off to nearest thousands = 1168

Answer:
B
Step-by-step explanation:
Unit rate means one quantity in terms of another unit quantity. In the answer choices, we see that the denominator is always in terms of UNIT LITERS (1 L), so that means, we have to find gallons in terms of UNIT LITERS.
It means, we have to divide gallons by liters to get in terms of unitary liters.
Let's check the first line:
19.5/75 = 0.26 Gallons / 1 Liter
Now, checking 2nd:
39/150 = 0.26 Gallons / 1 Liter
So, yes, they are the same and other 2 lines would be the same as well. The unit rate is:
0.26 gal/1L
That's answer choice B
