The inequality |2x − 6| less than or equal to 10 can be expressed as two form like this to get two value of x
2x-6 ≤ 10
2x≤10+6
x≤8

-(2x-6) ≤ 10
2x-6 ≥ -10
2x≥-10+6
x≥-4

The graph of the inequality would be: 
x≤8 and x≥-4
or
-4≤x≤8

Answer:

$Average\ Speed = 60 mi/hr$

Step-by-step explanation:

Given

$Distance = 345\ miles$

$Time = 5\ hours\ 45\ minutes$

Required

Determine the average speed

This is calculated as thus:

$Average\ Speed = \frac{Distance}{Time}$

Convert time to hour:

$Time = 5\ hours\ 45\ minutes$

$Time = 5\ hours + \frac{45}{60}\ hour$

$Time = 5\ hours + \frac{3}{4}\ hour$

$Time = \frac{20 + 3}{4}\ hours$

$Time = \frac{23}{4}\ hours$

$Time = 5.75\ hours$

$Average\ Speed = \frac{Distance}{Time}$

$Average\ Speed = \frac{345}{5.75}$

$Average\ Speed = 60 mi/hr$

If you divide 6! by 4! you are evaluating P(6, 4)

Aleks [24]

When you're evaluating P(n, k), you are essentially saying there are n objects and you will need to arrange them in k spaces.

This is essentially the same as: $^{6}P_4$ , which follows the formula:

$P(6, 4) = ^{6}P_4 = \frac{6!}{(6 - 4)!} = \frac{6!}{2!}$
If you're dividing by 4!, you are evaluating P(6, 2)

-104=8x what is x ????

love history [14]

$-104=8x \\ \\ - \frac{104}{8} = x \ / \ divide \ each \ side \ by \ 8 \\ \\ -13 = x \ / \ simplify \\ \\ x = -13 \ / \ switch \ solution \ around \\ \\$

The final result is, x = -13.

Answer: (3, 18)

Step-by-step explanation: Where the lines corss the x does not go over 10 so the only other option is a 3. If you cut the box hori in half in you mind, the top half being 15-20 and the bottom half bring 10-14, then you can see the lines cross on the top half. Meaning it’s at 18 not 12.
