Answer:
Answer B is wrong the correct answer is C. Cavities/ liter
-50
So you want to pair them up
(1-2)+(3-4)+(5-6)..+(99-100)
And write the answer for each pair
(-1)+(-1)+(-1)..+(-1)
When looking at this you can see that each pair equals -1
So you divide 100 by 2 and multiply that by the -1
100/2=50
50*-1=-50
Answer is 50
You would use the same method if you were going up to a number like a 500
The answer would be -250
The function is given in <u>point-slope form</u>, which is:
y₂ - y₁ = m(x₂ - x₁)
The equation they gave you is:
y - 4 = -3(x + 2)
An x of -2 and a y of 4 are in the equation:
(-2, 4)
Therefore, the point (-2, 4) lies on the line of the given equation, or B.

Answer:
18
Step-by-step explanation:
w varies directly with z, let k be the constant of proportionality, hence this can be represented by the equation:
w = kz
When z = 4, w = 12, hence we need to find the value of the constant of proportionality, substituting:
12 = 4k
Dividing both sides by 4:
12/4 = 4k/4
k = 3
Therefore the equation becomes:
w = 3z
The value of w when z = 6 is given as:
w = 3(6)
w = 18
