Since the population is going to increase by a certain percentage, we have to add to the percentage to keep the original population.
Now, convert the percentage into a decimal. You can do this by moving the decimal place two places to the left.
Now, just multiply that by .
Answer: Mckenzie is correct
<em>I had to reformat this section with the way it was typed, please let me know if I did anything wrong.</em>
<u>Mckenzie's Work</u>
a² + b² = c²
25 + 169 = c²
194 = c²
Square root 194 equals square root c squared.
c ≈ 13.93
<u>Cara's Work</u>
a² + b² = c²
25 + b² = 169
b² = 144
Square root b squared equals square root 144.
b ≈ 12
[] Right away we can tell that <u>Cara is not correct.</u>
-> Cara solves for b. We already have a b value, we need to solve for "c" in the equation.
[] Now let's look at Mckenzie.
-> Mckenzie does solve for the right variable, so let's see if she did it correctly.
-> First, she sets is up using a² + b² = c² since this is a right triangle. Next, she squares 5 to 25 and 13 to 169. Both correct.
-> Now they are added together. 25 + 169 do equal 194 so this looks correct.
-> Last, we square both sides. ≈ 13.928388 which rounds to 13.93, so it looks like <u>Mckenzie is correct</u>.
Have a nice day!

Answer:
C. –x + 8y = 56
Step-by-step explanation:
Write in standard form.
x − 8 y = − 56
This is a linear function in the slope - intercept form:
y = m x + b and we need a standard form:
a x + b y = c
y = 1/8 x + 7 / * 8 ( we will multiply both sides of equation by 8 )
8 y = x + 56
- x + 8 y = 56 / * ( - 1 )
x - 8 y = - 56
The equation is y = 1/8x + 7
Standard form equation is Ax + By = C, where A > = 0.
First eliminate the fractions by multiplying the equation by 8
8y = x + 56
Subtract x from each side
-x + 8y = 56
SInce x coeficient can't be negative multiply the equation by negative one.
x - 8y = -56
