Answer:

The only difference is: If you multiply or divide both sides of an equation by the same negative number, the equation remains the same, but If you multiply or divide both sides of an inequality by the same negative number, the inequality reverses. !!!!!

do you really need explanation? I don't know how to explain it to you I just calculated it gradually...

Answer:

[tex]\sf slope: \dfrac{5}{4}[/tex]

[tex]\sf y-intercept: 0[/tex]

explanation:

comparing with the formula: y = mx + b  

Here the input equation: y = 5/4 x + 0

[tex]\hookrightarrow[/tex] m = 5/4 and b = 0

The value of x can be found by using the formula for the area of a trapezoid. The value of [tex]$x$[/tex] is [tex]$4$[/tex] inches.

Area is a two-dimensional measurement that is used to measure the size of a shape or surface. It is measured in square units, such as square centimeters, square meters, square kilometers, and so on. The formula for the area of a trapezoid is: [tex](a+b)/2 *h[/tex], where a and b are the lengths of the parallel sides, and h is the height. Mrs. Katz needs to calculate the value of x by plugging in the lengths of the parallel sides and the height into the formula.

We know that the opposite sides of a trapezoid are parallel, so we have [tex]AB \parallel DC.[/tex]

Using the given information, we can set up an equation in terms of [tex]$x$[/tex] and solve for it. We know that the height of the trapezoid is [tex]$8$[/tex] inches, and we know that the bases are [tex]$x$[/tex] inches and [tex]$16$[/tex] inches.

Using the formula for the area of a trapezoid, we have:

[tex]\text{Area} = \frac{1}{2}(AB+DC)(\text{height})[/tex]

Plugging in the values we know, we get:

[tex]\text{Area} = \frac{1}{2}(x+16)(8)[/tex]

We are also given that the area of the trapezoid is [tex]$100$[/tex] square inches, so we can set up an equation:

[tex]100 = \frac{1}{2}(x+16)(8)[/tex]

Simplifying and solving for [tex]$x$[/tex], we get:

[tex]100 &= \frac{1}{2}(x+16)(8)\20 &= (x+16)\x &= 4[/tex]

Therefore, the value of [tex]$x$[/tex] is [tex]$4$[/tex] inches.

The rate of change or essentially the slope is a numerical value that describes the direction and the steepness of the line.

To find the slope, we just need any two points on the line

       --> Let's pick (0,2) and (2,6)

The slope's equation = [tex]\frac{y2-y1}{x2-x1}[/tex]

Let's plug the known quantities into the equation

     [tex]\frac{y2-y1}{x2-x1}=\frac{6-2}{2-0} =\frac{4}{2} =2[/tex]

Therefore the rate of change is 2 km/trip

Answer:

-5+(-3)

=-5-3

=-8

Step-by-step explanation:In a problem like this you have to write -3 in parentheses.

Since the + sign is outside the parentheses here, the -3 and + sign are multiplied.

+ saha- multiplication yields -sign.

So there's a -3 coming.

Then -5-3.

Since the sign of this is the same, the two numbers are added. In both - the mark is applied to the answer because there is a mark.

The volume of the rectangular prisms is given by 72 in³, 36 in³, 80 in³ and 54 in³

Volume is the amount of space occupied by a three dimensional shape or object.

The volume of a rectangular prism is given by:

Volume = length * width * height

a) Dimensions: 4 in., 3 in., 6 in.

Volume = 4 * 3 * 6 = 72 in³

b) Dimensions: 6 in., 3 in., 2 in.

Volume = 6 * 3 * 2 = 36 in³

c) Dimensions: 4 in., 5 in., 4 in.

Volume = 4 * 5 * 4 = 80 in³

d) Dimensions: 2 in., 9 in., 3 in.

Volume = 2 * 9 * 3 = 54 in³

The volume of the rectangular prisms is given by 72 in³, 36 in³, 80 in³ and 54 in³

The function represent the quadratic function is h(x) = 3x(x – 2) – 4, the correct option is D.

Quadratic equations are the polynomial equations of degree 2 in one variable of type f(x) = ax^2 + bx + c where a, b, c, ∈ R and a ≠ 0.

The function which represnt a quadratic function is;

[tex]\rm h(x) = 3x(x - 2) - 4\\\\ h(x)=3x\times x - 3x \times 2-4\\\\ h(x)=3x^2-6x-4[/tex]

The highest degree of the function is 2 so the function is the quadraic function.

Hence, the function represent the quadratic function is h(x) = 3x(x – 2) – 4.

24 minutes.

Let me explain.

The lawn can be any size, but for the purpose of simplicity, let's say it's 240 square meters.

Peter mows 6 square meters per minute if he mows 240 square meters in 40 minutes.

John mows 4 square metres each minute if he mows 240 square metres in 60 minutes.

They'll mow 10 square meters per minute if they work together.

As a result, mowing the entire lawn will take them 24 minutes.

(Note that the location is irrelevant as long as we know how long each man takes to complete the task separately.) The answer would be the same if the field was 1 million hectares in size.)
