EXTRA POINTS* how do you graph y = -3x - 9

Mathematics

1 answer:

Andreas93 [3]3 years ago

4 0

Answer:

See Below

Step-by-step explanation:

Ok, your equation is in slope intercept form (y= mx + b), where m is the slope and b is the y intercept.

y = -3x -9

y = mx + b

m = -3

b = -9

Soo, plot the y-intercept first. (-9)=> (0,-9)

Then go down 3 over 1 (do this twice) (in my case, down 9 over 3)

Then draw the line.

Three numbers are in the ratio 3:9:10. If 10 is added to the last number, then the three numbers form an arithmetic progression.

MrRa [10]

Answer:

 The numbers are 6, 18, and 30 

Step-by-step explanation:

If the three numbers are in the ratio of 3:9:10,

let the numbers be 3x, 9x and 10x.

If 10 is added to the last number to form an arithmetic progression

Then, 3x 9x (10x+10) are the progression

The common difference of an arithmetic progression (d) = T₂ - T₁ = T₃ - T₂

T₂-T₁ = T₃ - T₂ .............. Equation 1

Where T₁ = first term of the progression, T₂ = Second term of the progression, T₃ = third term of the progression

Given: T₁ = 3x, T₂ = 9x, T₃ = 10x +10

Substituting these values into equation 1

9x-3x = (10x+10)-9x

Solving the equation above,

3x = 10+x

3x-x = 10

2x = 10

x = 10/2

x = 2.

Therefore the numbers are 6, 18, and 30

What is the best way to display data if there is a wide range and we want to see individual data?

Novosadov [1.4K]

Answer:
The correct option is;
b. Stem and leaf plot

Step-by-step explanation:
A stem-and-leaf plot shows the data shape and the densities of the different classes in a graphical form such that the information in the data such as the data characteristics are self displayed by the data numbers arranged in the stem-and-leaf plot. The stem-and-leaf plot keeps the raw numerical data, in the form they were obtained and by their arrangement, outliers are easily spotted.

What is the solution of the proportion? 14/12 = D/48 a. 56 b. 672 c. 168 d. 576

Verdich [7]

So basically we can simplify the fraction by finding the gcf which is the greatest common factor so 14/12 both have 2 in common we simplify that by dividing by 2 so 14÷2 is 7/6 is the fraction on the left hand side and d/48 is the fraction on the right hand side so to solve for d we have to divide 336/6 whixh equals 56 as tour answer. Hoped this helped!!

Is Y=7.5x proportional or non proportional

kipiarov [429]

Hi , the answer is proportional , every time when you see an equation that has the Y first then a number next to a x , that equation tells you that there is a proportional relationship.
