Find an easy to read point such as (10, 40).
The ratio of y to x is 40/10 = 4/1.
Now look in your choices and find a point in which y is 4 times x.
The only such point is (5, 20).
Answer: C. (5, 20)
I would believe it would be something like; 120 miles: 2 hours, 800 lbs: 40 square inches...etc.
Hello from MrBillDoesMath!
Answer:
r = C/6.28
Discussion:
Note that C = 2 * Pi * r is the exact formula. As Pi is approximately 3.14, the given formula, C = 2 (3.14) r, is an approximation. Solving it for r:
C = 2(3.14) r => as 2 * 3.14 = 6.28
C = 6.28 r => divide both sides by 6.28
r ( 6.28/6.28) = C/6.28 => as 6.28/6.28 = 1
r = C/6.28
Thank you,

Step-by-step explanation:
-6x^2 -8x +2x-8 = -6x^2 -6x -8
it's a quadratic.
A linear pair of angles has a common side, and the vertex is on the line designated by the points denoting the non-common sides.
Consider the first choice:
... the common sided is RL, and the other two points are P and M. Point R (the vertex of the angles) is not on line PM. (In fact, line PM is not shown on the diagram.)
In the second choice, the given angles do not have a common side. (They are actually "vertical" angles.)
In the 3rd choice, the common side is RN, and vertex point R is found on line MO. These angles <em>are</em> a linear pair:
... - MRN and NRO
