Answer:
-383.5
Step-by-step explanation:
4+2.5+1+...-33.5
a=4
c.d. d=2.5-4=-1.5
l=-33.5
l=a+(n-1)d
-33.5=4+(n-1)(-1.5)
-33.5-4=(n-1)(-1.5)
-37.5=(n-1)(-1.5)

Answer:
B. {(-3, 4), (-8,0), (3, -8), (-3, -4)}
Step-by-step explanation:
B. is not a function because the x's repeat in this one.
If the x's repeat then it is not a function.
{(-3, 4), (-8,0), (3, -8), (-3, -4)}
The -3 repeats so it is not a function.
Y can repeat, but x cannot.

The only type of line with undefined slope is a vertical line.
In a vertical line, all points have the same x-coordinate.
The general equation of a vertical line is x = k, where k is the x-coordinate of all points on the line. If you are given one point, then you know the x-coordinate of that point, but since all points have the same x-coordinate, you also know the x-coordinate of all points.
Equation is: x = -6

Same explanation as above.
x = 2
1 ton= 2,000 pounds
250 x 8 = 2,000
final answer: it would take the elephant 8 days to eat a ton of food
