Answer:

Step-by-step explanation:
we know that
The Pythagorean Theorem states that in a right triangle

where
c is the greater side (the hypotenuse)
a and b are the legs
In this problem
Let
c=AB ---> distance from point A to point B
a ---> the difference of the x-coordinates both points
b ---> the difference of the y-coordinates both points
so

substitute




Answer:
f = 10/3
Step-by-step explanation:
-15 + 6f = 5
-15 + 15 + 6f = 5 + 15
6f = 20
6f/6 = 20/6
f = 20/6 = 10/3 = 3.333...
You could not do that then you would gey 110.25 which is what is not the question
Answer:
y = 3x + 3
Step-by-step explanation:
If the entire line, or rather, the graph, is translated upwards by 5 units; the slope stays the same, but the y-intercept rises by 5 as well. Thus, the equation of the new graph would be;
y = 3x (-2+5)
y = 3x + 3
3. 4y-3
because 1/3*12y - 1/3*9 = 4y - 3
