What is the solution set for the given inequality if the replacement set for r is {5, 6, 7, 8, 9, 10}?

tangare [24]

Answer:

{6,7,8,9,10}

Step-by-step explanation:

Solve the inequality using inverse operations.

$3r\leq 4r-6\\3r-4r\leq -6\\-r\leq -6\\r\geq 6$

This solution means values equal to or larger than 6 from the set are solutions. This means 6, 7, 8, 9, and 10 are the solution set.

Trava [24]

Answer:

y = $\frac{2}{5}$ x - 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = $\frac{2}{5}$ and c = - 3 , then

y = $\frac{2}{5}$ x - 3 ← equation of line
