Answer:

6a²+7ab-7a+17b-20b²-3

Step-by-step explanation:

3a(2a+5b-3)-4b(2a+5b-3)+1(2a+5b-3)

6a²+15ab-9a-8ab-20b²+12b+2a+5b-3

Collect like terms

6a²+15ab-8ab-9a+2a+12b+5b-20b²-3

6a²+7ab-7a+17b-20b²-3

A student has 8 pints of iced tea in a pitcher. The amount of iced tea in the pitcher is a function of x, the amount of iced tea
Reptile [31]

Answer: The domain is:

0 pints ≤ x ≤ 8 pints.

Step-by-step explanation:

When we have a function:

y = f(x)

The domain is the set of the possible values of x (the possible inputs).

In this case, the value of x represents the amount of tea that she has poured from the pitcher.

Now, initialy the pitcher has 8 pints, so the smallest possible value of x is 0 pints (when she has not pured anithing) and the maximum value of x is 8 pints (when she has poured all the 8 pints).

So we have the domain:

0 pints ≤ x ≤ 8 pints

Burka [1]

Answer:

x=1/4

Step-by-step explanation:

you would take a away 1/2 from each side so it would look like this

x+1/2=3/4

x=3/4-1/2

and 3/4-1/2 is 3/4-2/4=1/4

x=1/4
