5(r + 3) = 3r + 35.
What is the answer and please show how you got it

Answers

Answer 1

Answer:

r =10

Step-by-step explanation:

5(r + 3) = 3r + 35.

Distribute

5r+15 = 3r+35

Subtract 3r from each side

5r+15-3r = 3r+35-3r

Combine like terms

2r +15 = 35

Subtract 15 from each side

2r+15-15 =35-15

2r = 20

Divide by 2

2r/2 =20/2

r =10

Answer 2
5(r + 3) = 3r + 35
Remove parentheses
5r + 15 = 3r + 35
Move the terms
5r - 3r = 35 - 15
Collect like terms
2r = 20
Divide both sides
R = 10

Write the function in vertex form. y=x^2+5x-9

Answers

Answer:

The function in the vertex form is y = (x + 2.5)² - 15.25

Step-by-step explanation:

The vertex form of the quadratic function y = ax² + bx + c is:

y = a(x - h)² + k, where

a is the coefficient of x²h, k are the coordinates of its vertex pointh = [tex]\frac{-b}{2a}[/tex]k equals y at x = h

∵ The given function is y = x² + 5x - 9

a = 1, b = 5, c = -9

→ Use a and b to find h

∵ h = [tex]\frac{-b}{2a}[/tex]

∴ h = [tex]\frac{-5}{2(1)}=-2.5[/tex]

h = -2.5

→ Find y at x = -2.5

∵ y = (-2.5)² + 5(-2.5) - 9 = 6.25 - 12.5 - 9

∴ y = -15.25

k = -15.25

→ Substitute a, h, k in the vertex form above

∴ y = 1(x - -2.5)² + -15.25

∴ y = (x + 2.5)² - 15.25

The function in the vertex form is y = (x + 2.5)² - 15.25

Determine a relationship between the x- and y-values. Write an equation.

Answers

Answer:

X increasing by one and Y decrasees by 2

The correct relation between x and y is [tex]y=x-2[/tex].

Given information:

The table showing the values of x and y is:

x    1    2    3    4

y    -1   0    1     2

From the given table, it can be seen that with an increase in the value of x, the value of y also increases.

From the values of y, it can be seen that y increases by 1 unit with a unit increase in x.

The relation between x and y can be written as,

[tex]y=x-2\\y(1)=1-2\\y(1)=-1[/tex]

Therefore, the correct relation or equation between x and y is [tex]y=x-2[/tex].

Step-by-step explanation:

The course triangle can be used to determine the transition of course stages from one to the other with labels as in the image. The angle <ABC and <BCA depends on the type of triangle we draw. Here it is 60° each.

What is a course triangle ?

The three main elements of the course design triangle are objectives, assessments, and instruction. All three course components must be closely correlated with one another and take into account the course setting to produce a cogent learning experience.

The Olympic triangle is a sailing course that is frequently used in racing dinghies, especially at important regattas like State, National, and World Titles, and it was also used during the Olympics. 

When looking up the course towards the top mark, the start line is frequently tilted 5 to 10 degrees to the port end, or the left end, as opposed to how the start line would be if it were parallel to the wind.

To windward of the top mark, with a finishing mark and the committee boat serving as either end of the line, is the most adaptable location to establish the finishing line.

PLEASE PLEASE PLEASE HELP ME Which of these lines has a slope of -3?

Answers

D. Is the one which has slope -3

It is because the point of it’s slopes are
( 0,0) and (1,-3)
So the slope will be

(Y2 - Y1)/(X2-X1)
Hence -3 is the slope of graph D.

The equation of the line showing the slope of -3 is represented by the fourth graph in the image. The correct option is D.

What is a slope?

Slope or the gradient is the number or the ratio which determines the direction or the steepness of the line.

The line is passing through the points ( 0,0) and (1,-3). The slope of the line is calculated by using the formula below:-

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Slope = ( -3 -0 ) / ( 1 - 0 )

Slope = -3

Therefore, the equation of the line showing the slope of -3 is represented by the fourth graph in the image. The correct option is D.

The ellipse is centered at the origin, its major axis is horizontal, with length 8; the length of its minor axis is 4;

Answers

Consider we need to find the equation of ellipse.

Given:

Ellipse is centered at the origin.

Major axis is horizontal, with length 8.

The length of its minor axis is 4.

To find:

The equation of ellipse.

Solution:

Major axis is horizontal, so standard form of ellipse is

[tex]\dfrac{(x-h)^2}{a^2}+\dfrac{(y-k)^2}{b^2}=1[/tex]       ...(i)

where, (h,k) is center of the ellipse and length of major axis is 2a and length of minor axis is 2b.

Ellipse is centered at the origin. So, h=0 and k=0.

Major axis is horizontal, with length 8.

[tex]2a=8[/tex]

[tex]a=4[/tex]

The length of its minor axis is 4.

[tex]2b=4[/tex]

[tex]b=2[/tex]

Substitute h=0, k=0, a=4 and b=2 in equation (i).

[tex]\dfrac{(x-0)^2}{4^2}+\dfrac{(y-0)^2}{2^2}=1[/tex]

[tex]\dfrac{x^2}{16}+\dfrac{y^2}{4}=1[/tex]

Therefore, the required equation of ellipse is [tex]\dfrac{x^2}{16}+\dfrac{y^2}{4}=1[/tex].

Answers

Answer:

x=1 ,y=-5

Step-by-step explanation:

3x + 10y = 47

5x - 7y = 40

____________

21x + 70y = 329. equ 1

50x - 70y = 400. equ 2

subtract equ 1 from 2

=71x = 71

divide both sides by the 71

71/71 = 71/71

x = 1

_________

to find y

substitute x into either equ 1 or equ 2

am using equ 2

5x - 7y = 40

5(1) - 7y = 40

5 - 7y = 40

7y = 5 - 40

7y = -35

divide both sides by the coffecient of y

7y/7 = -35/7

y = - 5

  -14.8 = -3.2y

Divide both sides by -3.2.

  -14.8/-3.2 = (-3.2y)/-3.2

a librarian arranges 4356 books in rows , such that the number of rows is equal to the number of books in each row , find the number of books in each row.​

Answers

Answer:

66

Step-by-step explanation:

Given that:

Total Number of books = 4356

Number of books in a row = number of rows

Let number of rows = b

Then number of books in each row = b

Total number of books = (number of rows * number of books per row

Hence,

4356 = b * b

4356 = b²

Take the square root of both sides

Sqrt(4356) = b

66 = b

Number of books in each row = 66
