Here you go. I hope you get it.

The graph of the equation y = 8x - 6 is a straight line.

What is slope intercept form?

The slope intercept formula y = mx + b is used when you know the slope of the line to be examined and the point given is also the y intercept

(0, b).

Given is an equation, y = 8x - 6

Finding the coordinates,

Put x = 0, y = -6

(0, -6)

Put y = 0

8x = 6

x = 0.75

(0.75, 0)

Plotting the graph,

Hence, we will get a straight line of the graph.

If Mis a centroid of triangle WOR and WM = 16, what is WX?

8
24
10
32

Answers

Answer:

WX = 24

Step-by-step explanation:

Centroid of a triangle divides the medians of the triangle in the ratio 2 : 1

Therefore,

WM/ MX = 2/1

16/MX = 2/1

2MX = 16

MX = 16/2

MX = 8

WX = WM + MX

WX = 16 + 8

WX = 24

The value of the side WX  is equal to 24. The correct option is B.

What is the centroid of the triangle?

The center of the thing is represented by its centroid. The centroid of a triangle is the location where the triangle's three medians intersect. It can alternatively be described as the location where the three medians come together.

A line connecting a side's midpoint and the triangle's opposite vertex is called the median. Triangle is a shape made of three sides in a two-dimensional plane. the sum of the three angles is 180 degrees.

The centroid of a triangle divides the medians of the triangle in the ratio of 2: 1.

Here, the ratio of the two sides will be given as:-

WM/ MX = 2/1

Calculate the value of MX to get the value of WX.

16/MX = 2/1

2MX = 16

MX = 16/2

MX = 8

The value of WX will be:-

WX = WM + MX

WX = 16 + 8

WX = 24

Therefore, the value of the side WX  is equal to 24.

(for example, the answer - 8 is smaller than +2)?



b) Which 2 integers make the greatest sum (when they are added together)?

Answers

Answer:

a) -5 and 4 make the mathematically smallest number when multiplied together

b) 4 and -5 make the greatest sum

Step-by-step explanation:

-5 x 4 = -20

-3 x 4 = -12

-2 x 4 = -8

-1 x 4 = -4

-1 + -5 = -6

how can I find the slope to this I need help​

Answers

Answer:

Your slope is -1

Step-by-step explanation:

Find the change in x and the change in y and put it in change in y over change in x.

Δx = -1 - -2 = 1

Δy = -1 - 0 = -1

Slope = rise over run = Change in y over change in x =  Δy/Δx = -1/1

Therefore the slope is -1/1 which is written as just -1

Answers

The account must pay a 40 percent interest rate under Marcos.

A basic interest account is what?

A loan's or deposit's initial principal serves as the foundation for simple interest.

Contrarily, compound interest is calculated based on both the principal amount and the interest that is accrued on it each period.

Simple interest is simpler to compute than compound interest because it is just applied to the principal.

How do you find the value of x please help me( Look at the picture provived)

Answers

Answer:

x=5

Step-by-step explanation:

We know that a pentagon is in total 540 degrees. From this, we add all other numbers and set them equal to 540 to solve for x.

So, after adding all the angles and setting them equal to 540, we get this.

21x+435=540

21x=105

x= 5

If you want, plug 5 into x and see if it adds up to 540 to check

21(5)+435=540

On a coordinate grid, where is the center of this circle?
x² + y² = 2
A)
(-1, -1)
B)
(0,0)
(1.1)
D)
(2, 2)

Answers

Answer:

Option B) (0,0) is the correct answer.

Step-by-step explanation:

Given equation of circle is:

[tex]x^2+y^2 = 2[/tex]

The general form of equation of circle with center at (h,k) and radius r is given by:

[tex](x-h)^2+(y-k)^2 = r^2[/tex]

The given equation of circle can also be written as:

[tex](x-0)^2+(y-0)^2 = 2[/tex]

Comparing it with the general form of equation, we get

h = 0 , k = 0

So the center is (0,0)

Hence,

Option B) (0,0) is the correct answer.
