Answer:

Step-by-step explanation:

Choice b is the only one that has the first equation properly graphed. The boundary line for that equation will have intercepts that can be found by setting the opposite variable to zero.

x-intercept = 25/2 = 12.5 (on the positive x-axis)

y-intercept = 25/5 = 5 (on the positive y-axis)

That is, the boundary line has a shallow negative slope, and is shaded below. Only graph 'b' has such a line.

Answer:

The answer is C. 11/29

Step-by-step explanation:

Simplify the left side.

29a - 5 = 6

Move all terms not containing a to the right side of the equation.

29a = 11

Divide each term by 29 and simplify.

a = 11 /29
