What is the solution to the system of equations? y= =x-10
2x + y = 4
a (-8,6)
b (-6,16)
c (6,-8)
d (16,-6)

A

Step-by-step explanation:

If you work the equations, you will find -10 -2=-8

4 +2 =6

step-by-step explanation:

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
