(-3l^2w^3)(2lw^4) simplify express using exponents.

Answers

The simplified algebraic expression using exponents is $(-3l^2w^3)(2lw^4)$ simplifies to $-6l^3w^7.$

To simplify the given expression using exponents, follow these steps:

Multiply Coefficients: Multiply the coefficients (-3) and (2) to get -6.

Combine Like Bases: For the variables with the same base (l and w), add the exponents when they are multiplied together.

Here, $l^2 * l^1 = l^(2+1) = l^3$ , and $w^3 * w^4 = w^(3+4) = w^7.$

Final Simplified Expression: Combine the results from steps 1 and 2 to get $-6l^3w^7.$

Therefore, the simplified expression using exponents is $(-3l^2w^3)(2lw^4)$ simplifies to $-6l^3w^7$ .The expression has been simplified using the rules of exponentiation. This simplification helps in reducing the complexity of the expression and making calculations easier.

What is the slope of this line? Enter your answer as a fraction in simplest term in
the box.

Answers

The slope of the line is 1/4.

What is slope?

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx

where, m is the slope

Given points:

(0, 6) and (8, 8)

Now, slope = $(y_2 - y_1)/ ( x_2- x_1)$

slope= ( 8- 6)/ (8-0)

slope = 2/8

slope= 1/4

Hence, the slope of the line is 1/4.

#SPJ2

Answer:

$slope=(1)/(4)$

Step-by-step explanation:

The slope of a line can be seen as:

$(rise)/(run)$

Rise over run is the change in the y values over the change in x values. For example, in this graph, you would start on one of the points given. From there, you would move up first. After moving up a certain number of spaces, you would move to the side until you reach the other point.

In the graph, you would move up until you are in line with one of the other points. Starting at (-4,5), move up one space, then to the left 4 spaces to reach the point (0,6). Using the spaces moved in the rise over run:

$(1)/(4) =(rise)/(run)=slope$

Therefore, the slope is $(1)/(4)$ .

This is true for any two points on the line.

:Done

*When you move up, the number will be positive $((+y)/(x) )$ . If you move down, the number will be negative $((-y)/(x) )$ . If you move left, the number will be positive $((y)/(+x))$ . If you move right, the number will be negative $((y)/(-x) )$ . Keep this in mind. It is very important.

**Always move along the y-axis first, then move along the x-axis. If you do it the other way, the slope will be wrong.

Is the quotient of two rational numbers always a rational number? Explain.

Answers

The Quotient of two Rational Numbers is a Rational Number if and only if Numerator and Denominator are Multiples.

From Algebra, we know that a Rational Number is a Real Number of the form:

$x = (a)/(b)$ , $a, b\in \mathbb{N}$ , $x \in \mathbb{R}$ (1)

Where:

$a$ - Numerator.
$b$ - Denominator.
$x$ - Quotient.

The Quotient can be an Integer or not. In the first case, all Quotients have their equivalent Rational Numbers.

Now, if we divide a Rational Number by another Rational Number, then we have the following expression:

$x' = (x_(1))/(x_(2))$

If $x'$ is a Rational Number, then it must also an Integer and if $x'$ is an Integer, then $x_(1)$ and $x_(2)$ must be Multiples of each other.

The Quotient of two Rational Numbers is a Rational Number if and only if Numerator and Denominator are Multiples.

Answer:

Yes,

Step-by-step explananation

The quotient of two rational numbers is always rational, and the reason for this lies in the fact that the product of two integers is always an rational number.
