Answer:
The length of the hypotenuse of the triangle is about 14.14 units.
Step-by-step explanation:
You can determine this by using the Pythagorean Theorem.
a^2 + b^2 = c^2
To find the hypotenuse, take sides a and b (10 and 10) and square them. You get 100. When you add 100 and 100 together, you get 200, which equals c^2. Find the square root of 200 to find the hypotenuse.

Answer:
C
Step-by-step explanation:
The rule tells you that (x,y) -> (x + 1, y - 3), so you take each vertice and add one to the x-values, and subract 3 from the y-values.
(-6, 4) -> (-6 + 1, 4 - 3) which simplifies to (-5, 1)
(-3, -2) -> (-3 + 1, -2 - 3) which simplifies to (-2, -5)
(2, 1) -> (2 + 1, 1 - 3) which simplifies to (3, -2)
Answer:
Step-by-step explanation:
A) Let x represent minutes used, and C represent monthly charge. We are given two (x, C) pairs: (370, 133.00) and (530, 181.00)
We can use these in the 2-point form of the equation for a line.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
C = (181 -133)/(530 -370)(x -370) +133
C = 48/160(x -370) +133
C = 0.30x -111 +133
C = 0.30x +22
__
B) For x = 477 minutes, the charge will be ...
C = 0.30(477) +22 = $165.10 . . . . for 477 minutes
