find x and y this is geometry
complete the equation of the line through (-8,-2) and (-4,6). use exact numbers. We need to find out what y=?
Answer:y = 2x + 14
Step-by-step explanation:
First, you have to find the slope by using
In other words,
The slope is 2.
Then you plug the rest into point-slope form (you can use either of the points, I used the first one)
Remember that m is the slope.
Distribute the slope to the par
Step-by-step explanation: first you do this then that then this then that then this

Given the equation 5 + x - 14 = x - 7.
Part A. Solve the equation 5 + x - 14 = x - 7. In your final answer, be sure to state the solution and include all of your work.
Part B. Use the values x = -2, 0, 3 to prove your solution to the equation 5 + x - 14 = x - 7. In your final answer, include all of your calculations.
Answer:
x=0
Step-by-step explanation:
combine like terms on both sides of the equal sign
-9+x= x-7
move similar terms to the same side
-2=0x
divide both sides by x
x=0

Answer:
A) 2x²y³[tex]\sqrt{7xy^2}[/tex]
Step-by-step explanation:
[tex]\sqrt[3]{56x^7y^5}[/tex] = [tex]\sqrt[3]{(2^3)(7)(x^3)(x^3)(x)(y^3)(y^2)}[/tex] anything inside the radical raised to
the third power can be removed to
the outside of the radical
= 2(x)(x)(y) · [tex]\sqrt[3]{(7)(x)(y^2)}[/tex]
= 2x²y·[tex]\sqrt[3]{(7)(x)(y^2)}[/tex]
The population of a small town was 3500 in 2005. The population increases by 4% annually. A. Write an exponential growth function to represent this situation. B. What will the population be in 2025?
Answer: The population in 2025 will be 7669
Step-by-step explanation:
a) When we have an initial quantity A, and we have an increase of the X%, the new quantity is written as:
new quantity = A + A*(X%/100%) = A*(1 + X%/100%)
In this case, our initial quantity is 3500, the town's population in 2005.
And X% = 4%.
We know that each year, the population increases by 4%.
Then if P(1) is the population one year after 2005, this is:
P(1) = 3500*(1 + 4%/100%) = 3500*(1.04)
After another year, the population increases again:
P(2) = (3500*(1.04))*(1 + 4%/100%)) = 3500*(1.04)*(1.04) = 3500*(1.04)^2
Well, we already can see the pattern here, the population N years after 2005 will be:
P(N) = 3500*(1.04)^N
b) Now we want to know the population in 2025.
N represents the number of years after 2005, then we will have:
N = 2025 - 2005 = 20
2025 is 20 years after 2005.
Then the population in 2025 will be:
P(20) = 3500*(1.04)^20 = 7,668.9
And we can not have a 0.9 of a person, so we should round it up to the next whole number, then the population in 2025 will be 7669

This model of the backboard of a basketball goal is composed of a rectangle and a semicircle. What is the area of
the model of the backboard in square inches?
Answer:
deal with the rectangle first A = l X w
4 X 12 = 48 squared cm
semi circle
Area of a circle πr^2
12/2 = 6, radius = 6
π6^2 = 113.097335
113.097335/2 = 56.5486677
56.5 + 48 = 104.5 squared cm

Paul reduced his debt from $1600 to $400. What was the percent decrease?
Answer: 75%
Step-by-step explanation:
The debt went from $1,600 to $400.
Formula when calculating percent decrease is:
= (New price - old price) / Old price
= (400 - 1,600) / 1,600
= -75%
Paul reduced his debt by 75%
-2(3x + 2) > -6x - 4
Answer: All real numbers are solutions.
Step-by-step explanation:
−2(3x+2)≥−6x−4
Step 1: Simplify both sides of the inequality.
−6x−4≥−6x−4
Step 2: Add 6x to both sides.
−6x−4+6x≥−6x−4+6x
−4≥−4
Step 3: Add 4 to both sides.
−4+4≥−4+4
0≥0
