Cameron earn's $7 per hour at her after school job. The total amount of her paycheck varies directly with the amount of time she
polet [3.4K]

Answer:

Proportionality equation: y=7kx

Linear equation: y=7x

Step-by-step explanation:

So the amount that Cameron earns = 7/hr

Hours = x

And total earned amount = y

So we can form an equation from this for the total amount:

y=7x

But the question asks us for a proportionality equation so:

Proportionality constant = k

So we get the equation:

y=7*k*x

Which expression is equivalent to –4. 5 – 6. 2y? –6. 2y – 4. 5 –6. 2y 4. 5 6. 2y – 4. 5 6. 2y 4. 5.
Furkat [3]

To find the expression that is equivalent to -4.5-6.2y we will rearrange all the given options to find the equivalent expression.

The expression that is equal to -4.5-6.2y is  -6.2y-4.5.

Given options to us

  1. –6.2y – 4.5
  2. –6.2y + 4.5
  3. 6.2y – 4.5
  4. 6.2y + 4.5

<h3>Which expression is equivalent to –4.5 – 6.2y?</h3>

We need to find an expression that is equal to -4.5-6.2y.

Therefore, we will arrange each of the equations and then compare it our equation,

A. –6.2y – 4.5

-4.5 -6.2y

Since after arranging the expression it matches our equation this is the expression that is equivalent to our equation.

B. –6.2y + 4.5

4.5 - 6.2 y

Since even after arranging the expression it does not match our equation this is the expression is not equivalent to our equation.

C. 6.2y – 4.5

-4.5 + 6.2 y

Since even after arranging the expression it does not match our equation this is the expression is not equivalent to our equation.

D. 6.2y + 4.5

4.5 + 6.2y

Since even after arranging the expression it does not match our equation this is the expression is not equivalent to our equation.

Hence, the expression that is equal to -4.5-6.2y is  -6.2y-4.5.
