X=first week
y=second week
z=third week
t=fourth week
18 more one 2nd week than 1st
x+18=y
x=y-18
3rd week, 4 less than 2 times as second
z=2y-4
4th week, 92
ttal=382
x+y+z+t=382
sub waht we know
x=y-18
y=y
z=2y-4
t=92
y-18+y+2y-4+92=382
conbine line terms
4y+70=382
minus 70 boht sides
4y=312
divide both sides by 4
y=78

Answer:
This is a function, because for every x-value, there is exactly one y-value.
The domain is: {-5, -4, -3, -2}, and the range is {-2, -1, 0}
Let me know if this helps!
Answer:
These quotients are different because of what division means.
Step-by-step explanation:
When you divide you start with a total and break it into equal groups. If you started with three and broke them into groups of 1/5, that is different then starting with 1/5 and breaking into three groups.
If you had 3 cups of Chex mix and made servings of 1/5 of a cup. How many servings could you get? This is 3 divided by 1/5.
If you want to put tomatoes in 1/5 of your garden and you have 3 different tomatoes you want to plant. What fraction of the original garden will each type of tomato be in if they are evenly distributed.
2 x - 5y = 13
2 × -1 - 5 × -3 = 13
Answer:
(-1, -3)
