When ur looking at the graph of ur inequality, u will see a shaded region.....all the points in the shaded region are ur possible solutions. So when u plot ur ordered pair, if it falls in the shaded region, it is a solution...if it does not fall in the shaded area, it is not a solution.

The length of a rectangle is 15 and its width is w.

Fed [463]

A rectangle with sides 15 and w has perimeter

$2p = 2(15+w) = 2w+30$

We want this quantity to be at most 50, so it must be less than or equal to 50:

$2w+30\leq 50$

For the record, this implies that

$2w\leq 20 \iff w \leq 10$

So, the width can be at most 10.

Solve the literal equation for x.<br> y=5x-rx-5

Alchen [17]

Answer:

$x = \frac{y+5}{(5-r)}$

Step-by-step explanation:

Given the literal equation, y = 5x - rx - 5,

In order to solve for x, start by adding 5 on both sides of the equation:

y + 5 = 5x - rx - 5 + 5

y + 5 = 5x - rx

Next, factor out x from the right-hand side of the equation:

y + 5 = x(5 - r)

Finally, divide both sides by (5 - r) to isolate x:

$\frac{y+5}{(5-r)} = \frac{x(5 - r)}{(5-r)}$

$\frac{y+5}{(5-r)} = x$
