1.Muliply parenthesis by 2
2x+2-4=4
2.calculate the difference
2x-2=4
3.move constant to the right side and change its sign
2x=4+2
4.add the numbers
2x=6
5. Divide both sides of the equation by 2
x=3

is the slope of the line.
Substituting numerical values,
The equation of the line in standard form is 
.
Answer:
16
Step-by-step explanation:
Multiply it by 1/3 and it equals 16
In (A) statistics class Wilson's students earn a higher ratio of a's to b's.
<h3>
What are ratios?</h3>
- A ratio in mathematics describes how many times one number contains another.
- For example, if a dish of the fruit contains eight oranges and six lemons, the orange-to-lemon ratio is eight to six.
- Similarly, the lemon to orange ratio is 6:8, while the orange to total fruit ratio is 8:14.
To find the higher ratio:
Given -
- Geometry class = a:b = 12:20 = 3:5
- Statistics class = a:b = 11:15
As we can observe that 3:5 < 11:15.
Therefore, in (A) statistics class Wilson's students earn a higher ratio of a's to b's.

If a consistent system has an infinite number of solutions, it is dependent . When you graph the equations, both equations represent the same line<span>. If a system has no solution, it is said to be </span>inconsistent<span> . The graphs of the </span>lines<span> do not intersect, so the graphs </span>are parallel<span> and there is no solution.
Sorry, this is a general answer. I could not view the graph below...</span>
