Please help me on this :/

What were mkh company's cash flows from (for) operating activities in 20x1? $(180,300) $233,100 $268,200 $279,400?

Which is a true statement comparing the graphs of x^2/6^2-y^2/8^2 = 1 and x^2/8^2-y^2/6^2 the foci of both graphs are the same points. the lengths of both transverse axes are the same. the directrices of = 1 are horizontal while the directrices of = 1 are vertical. the vertices of = 1 are on the y-axis while the vertices of = 1 are on the x-axis.

Solve this equation using substitution. {4x + y = −2} {4x + 6y = 44}
