from the equal angles it is an isosceles triangle, AB = AC.

4x + 1 = 2x + 23

4x - 2x = 23 - 1

2x = 22

x = 22 : 2

x = 11

----------------------

4 * 11 + 1 = 2 * 11 + 23

45 = 45

--------------

now we find BC

3x - 8

3 * 11 - 8 =

25 (is the value of BC)

Is (2, 6) a solution to this system of equations? y = -x + 8 y = 5x - 4 yes no

Alexxx [7]

Answer:

Yes

Step-by-step explanation:

To see is (2, 6) is a system, we can plug it into the system to check if it gives us true statements:

6 = -2+8

6 = 6

6 = 5(2)-4

6 = 10-4

6 = 6

Both of the equations are true, therefore (2, 6) is a solution to this system.
