Question 11 :
the equations are :
now, let's graph the lines ~
As you can see in the attachment, The lines coincides each other, so the equations are :
Answer:

Step-by-step explanation:
I think this question is a bit hard to explain by typing, so I'll add an image down below.
I used long division for this question, and the final answer is: 
Answer:
B
Step-by-step explanation:
Answer:
c = 75 in
Step-by-step explanation:
The hypotenuse of a right triangle is found by the Pythagorean theorem:
<em>a² + b² = c²</em> (a and b are the legs, c is the hypotenuse)
Plug in: <em>45² + 60² = c²</em>
Square + square root: √(2025 + 3600) = c
Add: √5625 = c
Square root: 75 in = c (no negatives because we are finding distance)
