Answer:
A
Step-by-step explanation:
YOu can see the rental fee on the graph as the amount payed at zero miles. The charge is 50$ per 100 miles, 50/100= 0.5
The range is the values of y, or the values of f(x)
multiple every number in the { } by 3.2, you will get the range.
the answer is A
Point A would be zero; Point B, the end of the 1/2-hour time interval, would be 1/2 (representing 1/2 hour). Then Amy needs to subdivide the interval A to B into three equal time intervals and to determine the length of each of these subintervals.
I would begin with 1/2 and divide that by 3:
1
--
2
====
3
--
1
Inverting the fraction in the denom. and multiplying, we get
1 1 1
-- * ---- = -----
2 3 6
So Amy will spend 1/6 th of an hour, or 10 minutes, on each chore.
Note that 3 times 1/6 comes out to 1/2 (hour), which is were we started.
If you plug the values for a, b, and c into the Pythagorean Theorem, you can get x alone to figure out the side lengths:
x² + 3x² - 1² = 3x² + 1²
Combine like terms
4x² - 1² = 3x² + 1²
Subtract 3x² from both sides
x² - 1² = 1²
Simplify 1²
x² - 1 = 1
Add 1 to both sides
x² = 2
Square root both sides
x = 1.41421
Then, simply plug in that number for x on each side! It comes out to a weird number, but I don't see any other way to solve it...
Hope this helps :)

Zoe’s family saved 3 times so 2573 x 3 = 7725 pennies
sorry if it’s wrong :/
