The solution for a system of two linear equations is (0, 0). Which equation below could be one of the equations in the system? A

Answer:

y = -3x

Step-by-step explanation:

For the equation to be a part of a system, the point (0,0) must be a part of the line. Since y = -3x is proportional meaning b = 0, its y-intercept is (0,0). This means it must cross through and include (0,0). This is a part of the system.

1/2(x+10)= 1/4 (x-8) x= <br> (must be a fraction)

Alex_Xolod [135]

Answer:

$x=-9\frac{1}{3}$

Step-by-step explanation:

$\frac{1}{2}(x+10)=\frac{1}{4}(x-8)$

$\frac{1}{2}x+5=\frac{1}{4}x-2$

$\frac{1}{2}x-\frac{1}{4}x=-5-2$

$\frac{3}{4}x=-7$

$x=-\frac{28}{3}=-9\frac{1}{3}$
