Answer:
-10.2n - 1
Step-by-step explanation:
We have two expressions in variable n and we have to add the two expressions.
An important thing to note is that only like terms can be added. i.e. the term with "n" can only be added or subtracted to the term with "n". Similarly a constant can only be added or subtracted to a constant.
Thus, the two given expressions add up to -10.2n - 1
Answer:
y=1/3x+1
Step-by-step explanation:
- 1/3=slope or (m), (1,2) is 1=x1 2=y1
- formula is y-y1=m(x-x1)
- y-2=1/3(x-1) -----> distributive
- y-2=1/3x-1 -----> get y alone
- +2 +2
- y=1/3x+1
Answer:
The slope of this line would be undefined.
Step-by-step explanation:
In order to find the slope of a parallel line, we first need to find the slope of the original line. We can do this by using the slope formula.
m(slope) = (y2 - y1)/(x2 - x1)
m = (7 - 3)/(-4 - -4)
m = (7 - 3)/(-4 + 4)
m = 4/0
Since we cannot divide by 0, we know the slope to be undefined. Also, since parallel lines have the same slope, we know the second line to also have an undefined slope.

Step-by-step explanation:
The sum of angles is 180°, so the value of x is found by subtracting the given angles from 180°.
For example, ...
2. x = 180° -23° -68° = 89°

When a number of similar calculations are required, I like to enter the formula once and let a spreadsheet do the math. In the attached, the units of x are degrees. The problems are in order 1–4.
