Answer:
36-5y-y^2
Step-by-step explanation:
multiply 9 and 4 to get 36
expand to get -9y+4y=-5y
-y*y=-y^2
Answer:
B
Step-by-step explanation:
If we make a graph comparing the total cost of the milk and the gallons bought, it will be a straight line, which is a constant rate of change.
The numbers are 25 and -15.
Answer:

Step-by-step explanation:
They give us the slope so this makes it a lot easier.
Slope intercept formula is
y=mx+b
(m) is slope
(b) is y intercept
we can apply our slope into the formula
y=-3/2x+b
Now we can replace (y) with the (y) from the ordered pair they gave us (4, 10), and replace the (x) with the (x) from the ordered pair they gave us
(4, 10)
10=-3/2(4)+b
Now solve
10=-6+b
Add 6 to each side
16=b
Now we we put both our slope and intercept into the formula.

Answer:
4
Step-by-step explanation:
To begin with, convert both fractions into improper fractions:
and
.
Then convert the first fraction to ninths in order to add the two:
.
Then we add the two:
