For each part A through D below, the idea is to find the common factor between the terms, which you'll then use the distributive property to pull out.
==================================
Part A
3x + 18 = 3(x+6)
Note how we pulled out a 3. If we distribute it back in, we end up with 3x+18 again. The other problems are done in a similar fashion
==================================
Part B
2x - 14 = 2(x - 7)
==================================
Part C
6x + 4 = 2(3x + 2)
==================================
Part D
9x - 15 = 3(3x - 5)
There would be no way to solve unless the distance between them was discussed
Answer:
B,C,D
Step-by-step explanation:
Just treat 'i' as a placeholder (I know that it represents √-1, but just add 'i' as if it were a placeholder becaseu that is what it is.)
(3+i)-(2-2i)
distribute
3+i-2+2i
group
3-2+i+2i=
1+3i
answer is A
Answer:
f(x) = 
x
Step-by-step explanation:
The first thing we need to find is the slope of the line able to pass through the given two points. Right now we have <em>y = mx + b</em> (linear function equation) and we need to find <em>m</em>.
- Using the slope formula or
and plugging in the given points' x and y values:
= 
=
- The slope of the line is that for every 5 units the line goes upwards, it goes 2 units to the right.
Our equation is now <em>y = x + b</em>. If you were in need of it, <em>b </em>gives the line's y-intercept, the place where it hits the y-axis. In this case you do not need <em>b</em> because the only specified conditions in the problem are the units the line hits.
Our final equation is:
f(x) = x
