The width of Todor's area model is 5+3=8

The width of Todor's area model can be determined by factoring 10x² - 5x + 15. 10x², -5x, and 15 can be factored into

5(2x² - x + 3).

Since the greatest common factor of these terms is 5, Todor's area model can be represented as 5 multiplied by two rectangles.

The first rectangle would have a length of 2x² and a width of 5, and the second rectangle would have a length of x and a width of 3. Therefore, the total width of Todor's area model would be 5 + 3 = 8

Answer:

y = 3x - 6

Step-by-step explanation:

The equation is y = mx + b  

m = the slope

b = y-intercept

Slope = rise/run or (y2 - y1) / (x2 - x1)

Let's pick 2 points (0, -6) (2,0)

We see the y increase by 6 and the x increase by 2, so the slope is

m = 6/2 = 3

y-intercept located at (0, -6)

So, the equation is

y = 3x - 6

Answer:

f(2) = -1

f(x) = 1 the x value is equal to 0

Answer:

x= 3     y= 1

Step-by-step explanation:

4 * 3 (x)= 12 + 1 (y)= 13

5 * 3 (x)= 15 - 3*1 (y)= 15 - 3 (y)= 12

Both scenarios are now proven true.

The angle in the capital letter "L" measures 90°, making it a right angle.

A right angle is one that is exactly 90 degrees, or half of a straight angle. There is usually a quarter turn in it. The fundamental geometric forms, rectangle, and square, each have four angles that measure 90 degrees.

When two lines cross, and there is a 90-degree angle between them, the lines are said to be perpendicular. A few examples of 90-degree angles in real life include the angle between the hands of a clock at 3 o'clock, the angles between two neighboring sides of a rectangular door or window, etc.

Answer: When two variables vary inversely, the product of their values is constant. This means that x * y = k, where k is a constant.

We are given that y = 14 when x = 3, so we can use this information to find the value of k:

k = x * y = 3 * 14 = 42

Now that we know the value of k, we can use it to find the value of y when x = 7:

y = k / x = 42 / 7 = 6

So, y = 6 when x = 7.

The area, in square inches, of the floor in the scale drawing is, 300 inches²

Scale factor is a mathematical term, which we use to scale 2-dimensional and 3-dimensional shapes. Scale factor is a measure of similar figures. Those figures who look the same but are in different sizes.

For example, Two spheres look similar but could have different radii.

Given that,

The rectangular floor of a classroom is 40 feet in length

And 38 feet in width

length in scale drawing  =  20 inches

The area, in square inches = ?

Scale factor  = length in scale drawing/ length of floor

length in scale drawing = 20 inches

length of floor =  40 feet = 480 inches

Scale factor  =  20/480

                      =   1/24

Dimensions in scale drawing,

length of scale drawing =   length of floor x  Scale factor

                                       =   480 x 1/24

                                       =   20 inches

Width of scale drawing =  width of floor x  Scale factor      

                                       =   30 x 12 x 1/24

                                       =    15 inches

Area of scale drawing =  20 x 15

                                     =  300 inches²

Hence, the area is 300 inches²

Slope is 4 and represents the rate at which the water flows into the tank in liters per minute.

The correct option is B.

A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation.

Given,

Tank has 9 liters water already

By the table

Amount of water is 17 liters in 2 minutes

But there was 9 liters of water already

So, the tank filled in 2 minutes = 17 - 9 = 8 liters

Tank filled per minute = 8/2 = 4 liters

Amount of water in the tank can be written as

y = 4x + 9

where x is number of minutes

comparing it with slope form of equation

y = m x + c

slope m = 4

Hence, 4 is the slope that represents rate of the flow of water into the tank in liters per minute.

Answer: x=-3, y=-4

Step-by-step explanation:

System of equations is actually pretty simple.

Let me explain the two methods of solving a system of equations problem.

1. Elimination method

y-2x=2

-y=-x+1

In this approach, we will subtract or add the two equations together to eliminate one variable.

So in this problem, we'll organize -y=-x+1 like this:

x-y=1

Now we have

-2x+y=2

x-y=1

All we have to do now is add the two equations together and:

-x=3

x=-3

As you can see, the y variable is gone and we can find x by simply solving the rest.

Now we know that x=-3, let's plug in the value to get y.

x-y=1

-3-y=1

-y=4

y=-4

Therefore, x=-3, and y=-4

2. Substitution method

Let's go back to the problem.

y-2x=2

-y=-x+1

Now let's say that we will solve the problem using the substitution method.

In this approach, we will express one variable with the other.

So what we do is express y with x:

-y=-x+1

y=x-1

Now that we went through that process, we can plug in the y in the other equation:

x-1-2x=2

-x-1=2

-x=3

x=-3

Now that we now x=-3, let's plug that in to get y.

y=-3-1

y=-4

So the answer: x=-3, y=-4

Do you see the pattern?

System of equations problems are all about eliminating one variable and using the value of one to find the other.

To ensure that the frame is a rectangle, the carpenter needs to make sure that opposite sides of the frame have the same length.

In other words, the two 6-foot-long boards must be opposite to each other and the two 8-foot-long boards must be opposite to each other.

This way, the carpenter can ensure that opposite sides of the frame are parallel and that the angles between these sides are right angles, which are characteristics of a rectangle.

Additionally, the carpenter could use a square or a measuring tape to check that the angles between the two sides of each length are 90 degrees. This will confirm that the frame is indeed a rectangle.

The rowers travelled 7.5 miles upstream.

We can define relative speed as the speed of a moving body with respect to another. When two bodies move in the same direction, their relative speed is computed by their difference. But when two bodies are moving in the opposite direction, the relative speed is calculated by adding the speed of both the bodies.

Given here: The speed of the rowers in still water as 4 mph but since they are rowing upstream their relative speed will be equal to 4-3= 3 mph and while in downstream their speed is 5 mph

Now the distance they travelled on both ends of the river is equal

let they reach the upstream end in x hours and travel downstream for 4-x hours then we have

3x=(4-x )× 5

3x+5x=20

x=20/8

x=2.5 hours

P(t)=20t+3660 is the formula for the moose population.

We will consider x on the graph to be years since 1990 and y on the graph to be the number of Moose.

We have two points on the graph:(0,3560) and (5,3460)

Using the slope formula, we can find the slope of this line:

m=(y2 - y1)/(x2 - x1)  

Substituting the points in the slope formula:      

m=(3560-3460)/(5-0)

m=100/5                        

m=20                            

Now that we have the slope of the line, we can use the point-slope formula to find the equation for the line:

y - y1 = m(x - x1)                              

y - 3560=-20(x-5)
