2, 6 3/7
3, 2 8/9
4, 15 1/4
5, 9 2/3
6, 7 5/8
B 6
C 3
The base is 6.
In order to find this, we can set the legs equal to each other since legs have the same length in an isosceles triangle.
x + 1 = -x + 7
2x + 1 = 7
2x = 6
x = 3
Now that we have the value for x, we can plug into the equation to get the value for the base.
3x - 3 = base
3(3) - 3 = base
9 - 3 = base
6 = base
We can see that the lines intersect at: (-5,-3)
Step-by-step explanation:
Given system of equations is:
Lets convert the second equation in the same form as the first equation
Adding 3y on both sides
Dividing both sides by 3
The graph of equation can be plotted using manual graphing or any online graphing calculator
We will use the Desmos online graphing calculator to graph the equations (Picture attached)
We can see that the lines intersect at: (-5,-3)
