Answers
Answer:
I believe the answer would be b
Step-by-step explanation:
Solve equation 1 for the variable y
y = -5x
Plug this in for variable y in equation
4•(-5x) + 12x = 16
- 8x = 16
Solve equation 2 for the variable x
8x = - 16
x = - 2
so far we know this
y = -5x
x = -2
Use the x value to solve for y
y = -5(-2) = 10
which would give us the answer B

find the slope of the line through each pair of points. (9, 16) , (14, -12)
Answers
Answer:
slope = - [tex]\frac{28}{5}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (9, 16) and (x₂, y₂ ) = (14, - 12)
m = [tex]\frac{-12-16}{14-9}[/tex] = [tex]\frac{-28}{5}[/tex] = - [tex]\frac{28}{5}[/tex]
If the circumference of a circle is 36π, what is the length of a radius of the circle?
A. 6
B. 18
C. 36
D. 72
Answers
Answer:
The answer is 6 (A)
Step-by-step explanation:
The exact answer is 5.73, but I think in the question they are rounding to the nearest whole number, so the rounded answer is 6.
My work:
C = 2πr
r = C
2π = 36
2·π = 5.72958
An animal reserve has 20,000 elk. The population is increasing at a rate of 8% per year. This can be modeled by the function P(t) = 20,000 (1.08)^t where t represents time in years and P(t) represents the elk population. What is the estimated population of elk in 6 years?
Answers
Answer:
The answer would be 31,737 elks.
Step-by-step explanation:
You would solve this by multiplying 1.08 by the power of 6 which equals 1.586874322944. You would then multiply this number by 20,000 which equals 31,737.4865 but since you can’t have .4865 of an elk the answer is just 31,737.

The perimeter of the polygon is 12 in. What is the length of side x?
Answers
Answer:
2in
Step-by-step explanation:
Since we are not given the type of polygon, let the polygon be an hexagon. An hexagon is a 6 sides shape. The perimeter of the shape will be the sum of all the sides of the polygon
Perimeter of the polygon = 6L
Length is the length of the side
Given
Perimeter of the polygon = 12in
Substitute and get L
P = 6L
12 = 6L
L = 12/6
L = 2in
Hence the length of side x of the polygon is 2in

2 5/6 years is how many months
Answers
Final Answer: 34 months
Steps/Reasons/Explanation:
Hey there! Each year is 12 months. We can see that 2 years is already given. 2 years × 12 months = 24 months.
For [tex]\frac{5}{6}[/tex] we will multiply it by two to find the remaining amount of months. [tex]\frac{5}{6}[/tex] × [tex]2[/tex] = [tex]\frac{10}{12}[/tex]. This means that there is an extra 10 months of a year remaining.
Now we have to add them up. 24 months + 10 months = 34 months.
