Distribute the 1/7 to 14r and -56 which gets you 2r-8=-14. After that subtract 8 from both sides, then you will have 2r=-6. Divide both sides by 2 the you will have your answer r=-3.

Solve each inequality, graph the solution on the number line, and write the solution in interval notation
Lubov Fominskaja [6]

Answer:

(-\infty,+\infty)

Step-by-step explanation:

The given inequality is 3x-2>4 or 5x-3\leq 7

We group similar terms to obtain: 3x>4+2 or 5x\le7+3

Simplify to get:

3x>6 or 5x\le10

x>2 or x\le 2

This implies that the solution set is all real numbers.

The solution in interval notation is (-\infty,+\infty)

Must m, in the equation y=mx+b=, always be a positive number?
Nadya [2.5K]

Of course not. 

If the line rises higher as it goes from left to right,
then its slope ( 'm' ) is positive.

If it sinks lower as it goes from left to right,
then its slope ( 'm' ) is negative.
