Tenisha solved the equation below by graphing a system of equations. log3 5x=log5 (2x+8) which point approximates the solution for tenisha’s system of equations?

You can use grahical calculator to plot both graphs (see attached image). As you can see, the x-coordinate of intersection point is somewhere nearly 2.75, then you can calculate y-coordinate (or approximately count it from the diagram).

1. ;

2. .

Therefore, point (0.95, 1.42) approximates the solution for Tenisha’s system of equations.

Answer

A is the symbol for parallel lines AB and XY.

Explanation

B shows that line segment AB and XY are parallel, because there are no arrows, and line segments do not extend forever.

C shows that ray AB and XY are parallel, because there is one arrow, and rays only extend on one point.

Only A shows that line AB and XY are parallel. Lines extend forever, the A shows that AB and XY are parallel, since there are arrows in both directions above AB and XY.
