Answer:
m= -9
Step-by-step
this should work because (4+4)+(-9+1)=0 an
im sorry if this is wrong but im 99% sure this is right
i only put things in parenthesis to make things work better in my brain
Answer:
5
Step-by-step explanation:
A constant is a number by itself, without any variables.
As you can see, 4 and 3 are coefficients of 
and 
respectively.
Thus, 5 is the constant term.
P=2(x+y) perimeter equals two time the sum of x and y dimensions...
We are told that P=400 so
2(x+y)=400
x+y=200
x=200-y...
Now area is:
A=xy, using x found above we have:
A=(200-y)y
A=200y-y^2
The rate of change of the area is dA/dy
dA/dy=200-2y
The maximum area occurs when the rate of change is zero or dA/dy=0 so
200-2y=0
2y=200
y=x=100yd
So the maximum area enclosed is when y=x=100 which is a perfect square (as is always the case for a four sided enclosure with a given amount of material)
A=100^2=10000 yd^2
The answer is b. because it is the only line that is best fit for the graph
Step-by-step explanation:
|2x + 4| <= 5
We have -5 <= 2x + 4 <= 5.
Therefore -9 <= 2x <= 1 and -4.5 <= x <= 0.5.
