Answer:
(-1,-2)
Step-by-step explanation:
I graphed the equation on the graph below so you can see that (-1,-2) is a solution.
For this case we have the following expression:

What we must do in this case is to use one of the properties of the sum.
In this case, we must use the associative property.
The associative property states:

We have then:

Simplifying we have:


Answer:
the following is equal to (2x / 3 - 7) + 7
D. 2x / 3.
Answer:
6
Step-by-step explanation:
2:7 is like 2x:7x
7x=21
x=3
2*3=6
So we are given two points, say P1(4,7), P2(x,19).
Slope is given by
m=3=(y2-y1)/(x2-x1)=(19-7)/(x-4)
solve for x
3=(19-7)/(x-4)
cross multiply
3(x-4)=12
3x-12=12
3x=12+12=24
x=8
