Answer:

The constant of proportionality is the constant value of the ratio of two proportional quantities x and y, typically the equation is Y=KX. ... The constant of proportionality does is, the value of Y is dependent on how the given value of X is effected by the constant of proportionality.

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

Constant of proportionality means slope which can be represented as y=mx+b, y=kx and a ton of other stuff I don't know.

But lets take it as y=kx because it's easier. Constant of proportionality/slope is k so its C, 5.5.

Hi! The answer would be 10.

My favorite way to solve problems like this is to use a calculator.

On your calculator you are going to do 25 times 0.40 which is the percentage converted into a decimal.

Whatever you get should be your answer! You can do this with other problems also!

Sarah took the advertising department from her company on a round trip to meet with a potential client. Including Sarah a total of 10 people took the trip. She was able to purchase coach tickets for $230 and first class tickets for $1290. She used her total budget for airfare for the trip, which was $7600. How many first class tickets did she buy? How many coach tickets did she buy?

Answers

You can set up a system of equations for this problem. Let x = number of coach tickets and y = number of first class tickets. Then:

330x + 1220y = 12730 (cost of coach tickets plus cost of first class tickets is total budget)

x + y = 17 (number of coach tickets plus number of first class tickets is total number of people)

Solve the second equation for y to get y = 17 - x, then plug that into the first equation and solve for x:

330x + 1220(17 - x) = 12730

330x + 20740 - 1220x = 12730

-890x + 20740 = 12730

-890x = -8010

x = 9

Sarah bought x = 9 coach tickets. Plug that into the second equation and solve for y:

9 + y = 17

y = 8

Sarah bought y = 8 first class tickets.

A line with a slope of -2 passes through the point (-2,-3). What is the equation of this line?

Answers

Answer:

y = - 2x - 7

Step-by-step explanation:

Step 1:

y = mx + b      Slope Intercept Form

Step 2:

y = - 2x + b      Input Slope

Step 3:

- 3 = - 2 ( - 2 ) + b    Input x and y

Step 4:

- 3 = 4 + b       Multiply

Step 5:

- 7 = b      Subtract 4 on both sides

Answer:

y = - 2x - 7

Hope This Helps :)

m = -2

y = mx +c

-3= -2(-2) +c

-3 =4 + c , c = -7

The function
has the same amplitude as the function y = cos(x – 4) + 1.

The function
is a translation of the parent cosine function.

Answers

Answer: the function y = cos(2x) - 2 and the function y = cos(x) - 3

Step-by-step explanation: just took it

Function [tex]y=cos2(x)-2[/tex] and function [tex]y=cos(x)-3[/tex].

Function:A function in mathematics from a set [tex]x[/tex] to a set [tex]y[/tex] allocates exactly one element  [tex]y[/tex] to each element [tex]x[/tex]. The sets [tex]x[/tex] and [tex]y[/tex] are collectively referred to as the function's domain and codomain, respectively.Initially, functions represented the idealized relationship between two changing quantities. A planet's position, for instance, depends on time. In the past, the idea was developed with the infinitesimal calculus at the end of the 17th century, and the functions that were taken into consideration until the 19th century were differentiable (that is, they had a high degree of regularity).Solution -

The function which has the same amplitude as the function [tex]y=cos(x-4)+1[/tex] and is the translation of the parent cosine is as follows:

[tex]y=cos2(x)-2[/tex][tex]y=cos(x)-3[/tex]

Therefore, function [tex]y=cos2(x)-2[/tex] , and function [tex]y=cos(x)-3[/tex].
