There is more than one solution because there are two different numbers whose square is 9. One of them is +3. The other is -3.
The fundamental theorem of algebra says every non-zero single-variable polynomial of degree N has exactly N roots, counting multiplicity. Your polynomial is degree 2, so has 2 roots.
Answer:
Lower average yearly temperature because the cities receive insulation at a lower angle during the year
Step-by-step explanation:
It’s 540
Because for a triangular prism you use the formula (LWH) (Length • Width • height)
Answer:
O A. 
Step-by-step explanation:
To find the equation of the line, we need to know the slope and the y-intercept.
so, let's start by the slope. We need two points given in the graph.
(4, 5) and (-2, -3)
Then use the Slope-Formula to identify the Slope of the line.
m = slope
m =
Slope Formula
m =
subtract the second y from the first y / second x from first x
m =
Turn the fraction to positive because two negatives = positi-
m =
Simplify
m =
Final Answer
The slope of the line is
now what about the y-intercept?
The y-intercept is located at the y axis.
It determines how many units the graph goes up or down depending...
Well in this case, the y-intercept is negative because it is below on the yaxis
Then we must determine the y-intercept.
so we know is negative but it isn't exactly on a point so it is formed as a fra-
then we can determine it by seeing when it hits another unit (hard explainin)
y-intercept = -1/3
Final Answer: y = 
Answer:
the answer is 4
Step-by-step explanation:
if y=21 the we substitute in the main equation
21=8x-11
8x=32
x=4
