Determine the constant of Proportionality in the situation below

9966 [12]

a constant of proportionality is a number you have to multiply x by to get y.

y=kx is the equation that expresses the proportionality of x and y

in this case, 10 video games cost $145

the question's basically asking what you have to multiply 10 by to get 145

y= 145; x=10

k= y/x = 145/10=14.5

the constant of proportionality is 14.5

Item 11 Identify the independent and dependent variables. The equation c=0.09s gives the amount c (in dollars) of commission a s

diamong [38]

Answer:

C is dependent variable

S is independent variable

Step-by-step explanation:

Here, give the equation, we are told to identify the independent and the dependent variable

When we talk of the independent variable, it is that variable which values does not depend on whatever values the second variable in the equation has. It is that variable that is used to find the other variable in the equation

While the dependent variable depends on the values we input in the equation. It is the variable that we arrive at after plugging different values for the independent variable

now looking at the question, the equation we have is as follows;

c = 0.09s

To get the value of c which is the cost , we have to input different values of a. As is the amount in sales that we have that will yield the value of the commission to be received

Thus, we can categorically say that the values of the commission are dependent on the values we get from the sales

Hence, while commission represents the dependent variable, the values of the sales are the independent variables

A watch was bought for Rs 1200. At what labeled price should it be sold to gain 33.33% after 20% discount find SP with 13% vat o

fgiga [73]

Answer:

Lebeled Price of watch = Rs. 2000

Selling price pf the watch = Rs. 1600

Step-by-step explanation:

∴ S = L - 20% L
∴ S = 0.8 L ..... (1)
∴ S = P + (1/3)P
∴ S = (4/3) P ..... (2)
As we know, P = 1200
∴ S (4/3) × 1200
∴ S = Rs. 1600
1600 = 0.8L
∴ L = 1600 ÷ 0.8
∴ L = Rs.2000
∴ Lebeled Price of watch = Rs. 2000
Selling price pf the watch = Rs. 1600

Answer:

$\boxed{D. 3 {x}^{2} - x - 6}$

Given:

$f(x) = 3{x}^{2} - 4 \\ \\ g(x) = x + 2$

To Find:

$(f - g)(x) = f(x) - g(x)$

Step-by-step explanation:

$= > f(x) - g(x) = (3{x}^{2} - 4) - (x + 2) \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 3{x}^{2} - 4 -(x) - (2)\\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: =3{x}^{2} - 4 - x - 2\\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: =3 {x}^{2} - x - 6$
