Answer:
To ensure uniformity on an exam
Or
To test whether you can distinguish between the two formats
Step-by-step explanation:
Standard form is when a straight line equation is rearranged in the form:
Therefore y=2x+4 in standard form is
The slope-intercept form is when a a straight line equation is written in the form:
where m is the slope and c is the y-intercept.
The given equation is
This is already in slope-intercept form:
The standard form and slope-intercept forms are just formats.
Your instructor may restrict you to leave your answer in one of these formats maybe for uniformity on a test.
You may also decide to rewrite an equation in slope-intercept form, so that you can easily identify the slope and y-intercept easily for graphing purpose.
Answer: 
Step-by-step explanation:
Let the smallest angle be x.
Then, the middle angle is x+30.
The largest angle is 2x+30.
Angles in a triangle add to 180 degrees, so:
So, the angles measure
The fraction will be undefined on x=5 and x=-5
Step-by-step explanation:
The fraction is undefined on values that make the denominator of the fraction zero.
Given fraction is:
To find the values on which the denominator will be zero, we put the denominator equal to zero.
So,
The fraction will be undefined on x=5 and x=-5

Answer:
The answer the student got was correct.
Step-by-step explanation:
It could possibly be the process they got the answer from that was incorrect, but 5 is the correct answer.
Answer:
1 and 1/30 gallons
Step-by-step explanation:
First, convert all the fractions to a common denominator. I'm choosing 30.
1/3=10/30 1/5=6/30 1/2=15/30
Now, you can add them together to get 31/30, so a little more than a gallon
