Answer:
-(14 - 7x); 7(x - 2); 3x - 14 + 4x
Step-by-step explanation:
for -(14 - 7x) when the negative is distributed you get -14 + 7x which is still 7x - 14
for 7(x - 2) when multiplied in you get 7x - 14
for 3x - 14 + 4x when added together you get 7x - 14

<u>ANSWER: </u>
The slope of the given line y - 3 = (x - 5) is 1 and (5, 3) is a point on that line.
<u>SOLUTION:
</u>
Given, line equation is y – 3 = (x – 5)
We have to find the slope of the given equation along with a point on that line.
Now, if we observe, the given equation is in point slope form 
Where, m is the slope of the line and
is a point on the line.
Now by comparison of the two equations we can conclude that,

So, the point on the given line is (5, 3).
Hence, the slope of the given line is 1 and (5, 3) is a point on that line.
The radius is 1.703......
#1). The length of the whole circumference is (π · D) = 12π .
120° is 1/3 of 360°, so arc-AB is 1/3 of the whole circumference.
#2). 60° is 1/6 of 360°.
So arc-CD is 1/6 of the whole circumference (which is given).
#3). The circumference of the circle is (π·D) = 20π .
70° is (70°/360°) of the whole circle, so arc-XY
is (70/360) of the whole circumference.
#4). Sorry, I don't remember anything right now about
angles between chords.
I hope what I've given you so far is worth 5 points.
