Answer:
22.32
Step-by-step explanation:
When tan(θ)=.4107, you can go on your calculator and do the inverse which would be 22.32 degrees. If you are doing this on a calculator, make sure you go to mode and find Radian Degree and pick which one you need to find
Count how many plots are greater than 4, which in this case, is 8 children.
Set 2x=x²-3 to each other.
Subtract 2x from both sides and get the following
x²-3-2x
Rearranging the formula to make factoring easier, we get
x²-2x-3
Factor and you should get the following:
(x-3)(x+1)
set both equal to 0 and solve for x.
x-3=0⇒x=3
x+1=0⇒x=-1
Now plug both of these values back into one of your original equations to get your y-values. It does not matter which equation you plug your xs back into due to the fact they intersect at the same x, and thus will also intersect at the same y.
For times sake,
y=2x
plug in x=3 and get y=6
plug in x=-1 and get y=-2
Ergo, the equations y=2x and y=x²-3 intersect at
(3,6) and (-1,-2)
Answer:
here you go, hope it's right
7=-41-5
7=-36
false
7=3(3)-2
7=9-2
7=7
true
since one is true and one is false its not a solution of the system
