Graph 3y-2x=-18
hmm, ok, x intercept is at y=0 and x=9 so the point (9,0)
y intercept is at x=0 and y=-6 so (0,-6)
all the graphs hit that
ok, so we have 3y-2x>-18
it is > and not ≥ so it is a dotted line
it is one of the first 2
ok, test points
(0,0)
0>-18?
true
so (0,0) is in it
so it is the 2nd one

Answer:
-8x^2·y·z +3y·z^2 -4y
Step-by-step explanation:
It can be helpful to make sure the variables in each term are in alphabetical order. This makes it easier to see "like" terms. The variables in each term are ...
x^2 y z
y z^2
x^2 y z
y
Only the first and third terms are like terms, so those are the only ones that can be combined. Their coefficients are -7 and -1, so sum to -8. The combined term is of highest degree, so in standard form we list that term first.
= -8x^2·y·z +3y·z^2 -4y
Answer:
Where is problem 11. Next time add a picture so a person will be able to solve it.
Answer: 615 ft²
<u>Step-by-step explanation:</u>
There are 4 walls - <em>assume that the floor and ceiling are not being painted.</em>
2 walls are 17 ft by 9 ft ⇒ 2(17)(9) = 306 ft²
The other 2 walls are 18 ft by 9 ft ⇒ 2(18)(9) = 324 ft²
1 window is 3.75 ft by 4 ft ⇒ 1(3.75)(4) = 15 ft²
2 walls + other 2 walls - 1 window ⇒ 306 + 324 - 15 = 615 ft²
