The change in the X - coordinates from one point to another on a line is given by x₂ - x₁ = Δx.

We have the change in the X - coordinates from one point to another on a line.

In a slope ratio, the change in the X - coordinates from one point to another on a line can be represented as -

x₂ - x₁ = Δx

Therefore, the change in the X - coordinates from one point to another on a line is given by x₂ - x₁ = Δx.

Answer:

Step-by-step explanation:

The remaining work is to identify the values of x that make the factors zero:

4x +45 = 0

  x = -45/4 . . . . negative dimensions are not useful

x -10 = 0

  x = 10

The width is x, so the width is 10.

The length is 4x+5, so the length is 4·10+5 = 45.

The rectangle has a width, x, of 10 and a length of 45.

Answer:

The width is 22.5 feet and the length 45 feet.

Step-by-step explanation:

Let l represent the length of the rectangle and  w represent the width of the rectangle. The cost of the fence (C) is:

C = 2l + 2w + 2l + 6w

C = 4l + 8w

360 = 4l + 8w

360 = 4(l + 2w)

90 = l + 2w

l = 90 - 2w

Area (A) of rectangle = length * width

A = l * w

Put l = 90 - 2w

A = (90 - 2w)w

A = 90w - 2w²

The maximum area is at A' = 0, hence:

Differentiating gives:

A' = 90 - 4w

Put A' = 0

0 = 90 - 4w

4w = 90

w = 22.5 feet

l = 90 - 2w = 90 - 2(22.5) = 45 feet

Hence the width is 22.5 feet and the length 45 feet.

For the given parallelogram, the measure of angle B is 65° and the measure of angle D is 65°. The answer is the third option.

There are different types of quadrilaterals, for example: square, rectangle, rhombus, trapezoid and parallelogram.  Each type is defined accordingly to its length of sides and angles. For example, for a parallelogram, its the opposite sides are equal and parallel. For a parallelogram is noted too that the opposite angles are equal.

The question gives the values of the angle B and D in function of n.

Therefore, considering that the opposite angles of the  parallelogram (ABCD)  are equal, so D=B.  Thus,

6n-25=3n+20

6n-3n=20+25

3n=45

n=15°

Replacing the value of n in each angle (B and D). Then,

D=6n-25= 6*15-25= 90-25= 65°

B=3n+20= 3*15+20= 45+20 = 65°

Answer:

See the attached image below for the filled out chart.

===================================================

Explanation:

Part 1

Pick any term and subtract off its previous term

So for instance 4.2 - 4.1 = 0.1

Or you could say 4.3-4.2 = 0.1

Whichever pair you pick, you should find that the common difference is 0.1

This means we add 0.1 to each term to get the next term. Therefore, the recursive rule is [tex]a_n = a_{n-1} + 0.1[/tex] which says "add 0.1 to the (n-1)th term to get the nth term". The (n-1)th term is the term just before the nth term.

The first term is [tex]a_1 = 4[/tex] as shown in the given sequence 4, 4.1, 4.2, ...

------------------------------

Part 2

We'll follow the same idea as part 1.

Subtract any two adjacent terms

-10-(-7) = -10+7 = -3

We add -3 to each term to get the next. This is the same as subtracting 3 from each term, which is reflected in [tex]a_n = a_{n-1}-3[/tex]

The first term is [tex]a_1 = -1[/tex]

Everything is summarized in the diagram below.

Answer:

The product can be calculated.

The resulting matrix will have 3 rows and 3 columns.

Step-by-step explanation:

Matrix multiplication

To find the product of two matrices is only possible when the number of columns of the first matrix is equal to the number of rows of the second matrix.

If X is the first matrix with dimensions (n x m) and Y is the second matrix with dimensions (m x p), the product XY is possible and the dimensions of the resulting matrix are (n x p).

Matrix A has two rows and three columns (2x3)

Matric C has three rows and two columns (3x2)

If we wanted to calculate the product CA, the number of columns of C must be equal to the number of rows of A.

Since both numbers are 2, the product can be calculated.

The resulting matrix will have 3 rows and 3 columns.

Hope This Helps :)

Answer:

It depends if it is in a word problem or on a graph

Step-by-step explanation:

In a word problem you are looking for 2 numbers one that is a rate and one that is a beginning number. The rate is going to be the slope and the beginning number is going to be the y-intercept.

The equation is y=mx+b

The m is the slope and the b is the y-intercept

On a graph wherever the line crosses through the y-axis that is the y-intercept  or the b in the equation. To find the slope however is a little more difficult you have to rise over run it. This means that you find a point that is perfect or a (pretty point). Then you go up from the y-intercept to the x line that it is resting on and then you go over to that point.

In the equation provided the y-intercept is 3 or (0,3) and the slope is 1/4 so you go up 1 and over 4 and you would get your next point (4,4). Hope this helps.

Answer:

The x-intercept of the function is 13 which represents the number of hours until all the snow has melted.

Step-by-step explanation:

Since there were 0 inches of snow on the lawn after 13 hours, the x-intercept of 13 represents the number of hours after the storm stopped when all of the snow had melted away.

Have a good day :)

The x-intercept of the function is 13 which represents the number of hours until all the snow has melted.

A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.

Since there were 0 inches of snow on the lawn after 13 hours, the x-intercept of 13 represents the number of hours after the storm stopped when all of the snow had melted away.

Hence, the x-intercept is 13.

Answer: D.) 18x+36

-4/3×6=-8

-8+44=36

6×3x=18x

I hope this is good enough:

Answer: The slope of the line can be determined from the gradient equation, rise (y axis)/ run (x-axis)

Hence let (-1, 8) be A and (2, -4) be B. The slope from A to B is (-4-8)/(2-(-1))= (-12)/3= -4

Hence the gradient/ slope of the line is -4.
