Answer:
Part 1) The solution of the system of equations is (2,-5)
Part 2) The solution of the system of equations is (2,4)
Step-by-step explanation:
Part 1) Linear combination
we have
-----> equation A
-----> equation B
Multiply equation B by 2 both sides

-----> equation C
Adds equation A and equation C

Find the value of y




The solution of the system of equations is (2,-5)
Part 2) By graph
-----> equation A
-----> equation B
we know that
The solution of the system of equations is the intersection point both graphs
Using a graphing tool
The intersection point is (2,4)
therefore
The solution of the system of equations is the point (2,4)
see the attached figure
Answer:
4%
Step-by-step explanation:
First, we turn this into a fraction:
3/75 = 1/25 = 4%
So 3 is 4% of 75
You use a number line to see what is greater and less than.
And use a model to visualize it more.
And they are alike because they can both help in the same way but for different people.
Answer:
They're the same angle. I would look up transversals so you could understand it a bit more. I'll upload a picture of a transversal in my answer but you should search it anyways.
Anyways,
To solve, you set 160 equal to the other side.
160 = 3x + 10
150 = 3x
x = 50
Help you with what because I don't see anything?
