Answer:
1. 1/2
Step-by-step explanation:
With a graph that has easily see-able points, slope can be calculated with rise over run, or change in y divided by change in x

What does the
mean? From any point, the next point will be up one and over to the right two. Since the graph is going from bottom left to top right, it is positive.
Have a nice day!
I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)

=

Since the two fractions have a common denominator already, we can just subtract the numerators.
b-3b=-2b or -3b+b=-2b
Either way you get the same answer :)
Our new fraction is

Now we know that this must be equal to

Again, since the denominators are already the same of course they are equal. 13=13
Now we have to set the numerators equal
-2b=8
Use inverse operations to get b alone
-2b=8
÷-2 ÷-2
b=-4
If you have any questions, feel free to ask. Hope this helped! :)
Answer:
No, the triangles are not similar
Step-by-step explanation:
The (reduced) side length ratios, shortest to longest, are ...
12 : 18 : 20 = 6 : 9 : 10
and
5 : 12 : 13
These are not the same, so the triangles are not similar.
The answer is the third one: 32 inches
(x, y)
Domain = x
Range = y
It is a function when none of the x values are repeating.
Answer - C) Both A and B
Hope this helps and makes sense!!
