By substitution.
Get y or x alone then insert it into the other equation solving for one of the two variables. After that substitute ur answer into one of the equations then solve.
Answer:
The correct answer is D because they are unknown
Step-by-step explanation:
Based on the information given the percentage increase is 5%.
<h3>Percentage increase</h3>
Using this formula
Percentage increase=Population several years later-Population for year/Population for one year×100%
Let plug in the formula
Percentage increase=236,360-225,000/225,000×100
Percentage increase=5%
Inconclusion the percentage increase is 5%.

First follow the order of operations so do the parentheses first.
30-2(7+2)-1
30-2(9)-1
Then multiplication
30-18-1
Then left to right
12-1
Then again
So your answer is 11

Answer:
1st option
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (- 3, 7) and (x₂, y₂ ) = (9, - 1)
m = 
= 
= 
= - 
, then
y = - x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (9, - 1 ) , then
- 1 = - 6 + c ⇒ c = - 1 + 6 = 5
y = - x + 5 ← equation of line
