Which of the following is the correct solution to the linear inequality shown below?
Georgia [21]
Correct answer is C.

Line y=\frac{1}{3}x-2 intersects y-axis at -2 and passes through the point (3,-1).

Line must be dashed, because the inequality sign is ">".

Point (0,0) must lie in the solution set because it satisfies inequality y>\frac{1}{3}x-2.

0\ \textgreater \  \frac{1}{3}\times 0-2

What is 1/2(4x+14)=2(x-7)
GREYUIT [131]

Answer:

no solution

Step-by-step explanation:

1/2(4x+14)=2(x-7)

Multiply both sides by 2.

4x + 14 = 4(x - 7)

4x + 14 = 4x - 28

Subtract 4x from both sides.

14 = -28

Since 14 = -28 is a false statement, there is no solution for this equation.

Answer: no solution
