Selection A works best.

_____
The other choices get you to a place where further work is necessary. They don't really contribute to solving the equation.

A) is the correct answer. 

3x + 3 = 6x
3x-3x + 3 = 6x - 3x
(3x -3x cancel each other out, leaving you with 3)
3 = 3x
3/3 = 3x/3
1 = x
x = 1

Now Verify- 
3x + 3 = 6x
3(1) + 3 = 6(1)
3 +3 = 6
6 = 6

Now can also use the guess and check way. But this is my way of solving it. I hope it helped.

Does the chart below represent a proportional relationship? What is the rate of change?
Lilit [14]

This chart represents a proportional relationship. The rate of change will be 4.

<h3>What is the constant of proportionality?</h3>

Firstly, there is a proportional relationship.

Two values x  and y are said to be in a proportional relationship if x=ky, where x and y are variables and k is a constant.

The constant k is called the constant of proportionality.

Given;

x y

1 4

2 8

3 12

4 16

Here, x = ky

put the first value

k = 1/4

This chart represents a proportional relationship.

So the rate of change will be

Rate = \dfrac{y_2 - y_1}{x_2 - x_1}\\\\Rate = \dfrac{8 - 4}{2 - 1}\\\\Rate = 4

Shelley wants to purchase a cell phone package, which includes a free phone. The cost of the package is $0.10 per minute, for th
GarryVolchara [31]

Answer:

The function would be linear because the rate of change is constant.

Step-by-step explanation:

Given

Base= \$89.00

Rate = \$0.10 per minute

See attachment for complete question and options

First, we write the function that calculates the cost (C(t)) for t minutes.

This is calculated as:

Cost = Base + Rate * t

C(t) = 89.00 + 0.10 * t

C(t) = 89.00 + 0.10t

Rewrite as:

C(t) = 0.10t + 89.00

A function that has the above format is referred to as a linear function which has the general format

f(x) = mx + b

Where

m represents the slope/rate and it is constant

From the list of given options, (a) is correct.
