The equation y=7.6x represents a proportional relationship what is the constant of proportionality?
prisoha [69]

Answer:

Option B. 7.6

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

where

k is the constant of proportionality

The slope of the linear equation is the same that the constant of proportionality

In this problem we have

y=7.6x

so

the slope is m=7.6

therefore

The constant of proportionality k is k=7.6

The sales tax for an item was $8.80 and it cost $440 before tax.
PilotLPTM [1.2K]

Answer:

Step-by-step explanation:

In non-mathematical form, the question is asking $8.80 is what percent of $440. N will equal the percent. So, you would set up the equation like this: 20 = N · 440

You need to solve the equation.

20/440 = N · 440/440

0.045 repeating = N

Rounded, the sales tax rate would be 4.5%

For what real values of $c$ is $x^2 - 8x + c$ the square of a binomial?
nikklg [1K]

Value of c is 16 for which equation  f(x) = x^2-8x+c  is a square of binomial !

<u>Step-by-step explanation:</u>

Here we meed to find the value of c for which equation f(x) = x^2-8x+c or ,  f(x) = x^2-8x+c is a square of a binomial . Let's find out:

We know that

⇒ (x-a)^2 = x^2-2(a)(x)+a^2   ..........(1)

Let's simplify given equation in question

⇒ f(x) = x^2-8x+c

⇒ f(x) = x^2-2(4)x+c

Comparing this equation with (1) we get :

a=4 , c=a^2

⇒ c=a^2

⇒ c=4^2

⇒ c=16

Therefore , Value of c is 16 for which equation  f(x) = x^2-8x+c  is a square of binomial !
