Point and line
Explanation : Parallel lines are two or more lines that do not intersect in any point. This definition uses "point" and "line," which are two of the undefined terms in geometry.

It looks like the 4th one is the one you want to investigate. There are two ways you could do it.
- You could remove the brackets
- You could substitute as in y^2 - 5y - 8 ie y = x^2 - 4.
I think the second way is easier to do. You will wind up with a quartic (x^4) the first way.
let y = (x^2 - 4)
Therefore z = y^2 - 5y - 6
This factors into
z = (y - 6)(y + 1)
Now put (x^2 - 4) in for y
z = (x^2 - 4 - 6)(x^2 - 4 + 1)
z = (x^2 - 10)(x^2 - 3)
So it looks like I either made the wrong guess, or I made a mistake.
Let's try the first one
Let y =x + 2
y^2+2y -8
=(y +4)(y - 2)
=(x+2 + 4)(x + 2 - 2)
=(x+ 6)(x)
Looks like the first one is the answer.

Answer:
18
Step-by-step explanation:
There are two areas where the circles P and C overlap. One is labeled "4" and the other is labeled "3x". The sum of these two values is the number of people who like Pop and Classical music, 13.
4 + 3x = 13
3x = 9 . . . . . subtract 4
x = 3 . . . . . . divide by 3

We are asked to find the number of people who like two types only. The three regions where only two circles overlap are labeled x, 3x, and 6. The answer to the question is the sum of these values.
like 2 types only: x +3x +6 = 4x +6 = 4(3) +6 = 18
18 students like two types of music only.
Answer:
You would be able to go 165 miles in total
Step-by-step explanation:
You are going 60 miles per hour, so that instantly brings you up to 120 miles, because you are there for 2 hours and 45 minutes. Because you are going exactly 60 mph, and each hour is 60 minutes, you can compare that you go 1 mile per minute. If this statement is true, you'll go another 45 miles, bringing you to a grand total of 165 miles.
Answer:
y = x+2
Step-by-step explanation:
(x1,y1) is (-4,-2) and (x2,y2) is (2,4)
Slope intercept form is y = mx+b
m = slope
b = add on
Slope = 
Substitute numbers
Slope = 
Two negatives = one positive
Simplify
The slope is 1
We can substitute y, x, and the slope
4 = 2*1 + b
4 = 2+b
b = 2
Slope intercept form is y = mx+b
Answer is y = x+2
Hope this helps :)
