Answer:
y = -3x - 5
Step-by-step explanation:
First find the slope: (-20 - 1) / (5 - (-2)) = -3
Then plug in one set of points into the equation y = mx + b.
1 = -3(-2) + b
1 = 6 + b
b = -5
So you can get the equation: y = -3x - 5
Answer:
m=-1
Step-by-step explanation:
Since you no what x is you can subst. it into the second equation so 2m+11-9=0 so 2m+2=0 then subtract 2 from both sides 2m=-2 than divide m=-1
Simply put, it says that the numbers can be added in any order, and you will still get the same answer. For example, if you are adding one and two together, thecommutative property<span> of addition says that you will get the same answer whether you are adding 1 + 2 or 2 + 1. This also works for more than two numbers.</span>

Answer:
92 m
Step-by-step explanation:
Use the Pythagorean theorem to find the length of the shorter side.
Let w = length of the shorter side.
The perimeter is 2l + 2w = 2(30) + 2(16) = 60 + 32 = 92 m
