Step-by-step explanation:

The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined. The range is the set of all valid y values. The domain of the expression is all real numbers except where the expression is undefined.

Answer:

Step-by-step explanation:

12nl-4=8 start by adding 4 to both sides.

12nl=12/l Divide both sides by l.

12n=12 then divide both sides by 12.

n=1/l

Answer:

A student who runs 3/4 mile in 6 minutes is faster than a student who runs 1/2 mile in 5 minutes because when you simplify both fractions to per minute, the student who ran 3/4 mile in 6 minutes (1/8 mile per min) ran faster than the student who ran 1/2 mile in 5 minutes (1/10mile in 1 min).

Step-by-step explanation:

[tex]\frac{3/4mile}{6min}[/tex] divided by 6 to get per min =

1/8 mile per min

Answer:

Step-by-step explanation:

To find the common ratio ( r) of a given sequence , divide the previous term by the next term.

That's

[tex]r = - \frac{51}{17} = - 3 \: \: \\ or \\ r = - \frac{153}{51} = - 3[/tex]

Since the common ratio is the same for any of the terms chosen , the common ratio is - 3

Hope this helps you

Answer:

|24 - (2x - 6)| < 6

x > 12 or x < 18 (12 < x < 18)

Step-by-step explanation:

Area of the triangle = ½*base*height = ½*8*6 = 4*6 = 24 unit²

Area of rectangle = length * width = (x - 3) * 2 = (2x - 6) unit²

Difference in their areas is given as less than 6. This can be represented as an absolute value of inequality as shown below:

|24 - (2x - 6)| < 6

Solve to find the solution of the inequality by splitting into two as follows:

24 - (2x - 6) < 6 OR 24 - (2x - 6) > -6

Solve for each

24 - 2x + 6 < 6

30 - 2x < 6

Subtract 30 from both sides

-2x < 6 - 30

-2x < -24

Divide both sides by -2. < will change to >, since we are dividing by a negative number.

x > 12

Or

24 - (2x - 6) > -6

24 - 2x + 6 > -6

30 - 2x > -6

Subtract 30 from both sides

-2x > -6 - 30

-2x > -36

Divide both sides by -2

x < 18

The solution of the inequality is x > 12 or x < 18

Or can be written as: 12 < x < 18

Answer:

The rectangle is 18 square inches

Step-by-step explanation:

A rectangle has Length that is twice its Width.

The Width = 3.

What is the area of the rectangle?

First, we know that L, the length, is 6 (twice as long as its width).

Remember that the area of a rectangle is Length times Width:

A  =  L W

and so

A  =  6  ×  3  =  18

The rectangle is 18 square inches

Answer:

A. (±[tex]\sqrt{10}[/tex])

Step-by-step explanation:

To find the value of x, you have to square both sides of the equation. [tex]\sqrt{x^{2} }[/tex] cancels out to just [tex]x[/tex], so you're left with [tex]x=[/tex]±[tex]\sqrt{10}[/tex].

Answer:

[tex]m=\frac{9}{7}[/tex]

Step-by-step explanation:

Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Simply plug in the 2 coordinates into the slope formula to find slope m:

[tex]m=\frac{-4-5}{-1-6}[/tex]

[tex]m=\frac{-9}{-7}[/tex]

[tex]m=\frac{9}{7}[/tex]
