y2-y1 / x2-x1 is how to get slop3 for 2 points (x1,y1) and (x2, y2). So 4-1 / 2-0 and the slope is 3/2. If this is right could you possibly give me brainliest? Hope this helped.
The scale factor from A to B is 5/3 and the value of r is 33/5
<h3>The scale factor from A to B</h3>
From the figure, we have the following corresponding sides
A : B = 5 : 3
Express as fraction
B/A = 3/5
This means that, the scale factor from A to B is 5/3
<h3>The value of r</h3>
From the figure, we have the following corresponding sides
A : B = 11 : r
Express as fraction
B/A = r/11
Recall that:
B/A = 3/5
So, we have:
3/5 = r/11
Multiply by 11
r = 33/5
Hence, the value of r is 33/5

rational numbers are always negative when u add irrational numbersStep-by-step explanation:
Answer:
I believe the answer is the system has one solution. Both lines have the same y-intercept. And the solution is the intersection of the 2 lines.
Answer:
Combination
Step-by-step explanation:
Permutation is likely used more for lists/ordered things.
Combination is used more for groups.
Since we are trying to elect a group of people (president, vice president, and secretary) out of 205 students, we use combination.
