Answer:
Part a) We should try to eliminate the y's because the coefficients are the same
Part b) The solution is the point (6,-9)
Step-by-step explanation:
Part a) Which variable pair should we try to eliminate?
we have
----> equation 1
----> equation 2
Solve by elimination
We should try to eliminate the y's because the coefficients are the same
Part b) What is the solution to the system?
Multiply equation 2 by -1 both sides
-----> equation 3
Adds equation 1 and equation 3
Find the value of y

The solution is the point (6,-9)
The answer to this question is 4v+8
12v+3-6v-9=2v-14+w
12v+3-6v-9-2v+14=w
12v-6v-2v+14-9+3=w
6v-2v+5+3=w
4v+8=w
G -1/6= 1/6
Move -1/6 to the other side
sign changes from -1/6 to 1/6
G-1/6+1/6=1/6+1/6
G = 2/6
Reducing: divide by 2 for 2/6
2/2= 1
2/6= 3
Answer : G= 2/6= 1/3
Check the picture below.
the quadrilateral is a parallelogram, thus the diagonals bisect each other, so, we could have used either diagonal, and get the same midpoint.
Here we have , f(x) = y= 7x-6
To find the inverse function of the given function, we need to follow some steps, which are:
First we need to switch x and y, that is
x= 7y-6
Next step is to solve for y, and for that, we need to add 6 to both sides
x+6=7y
Dividing both sides by 7, that is
Therefore,
