Use Pythagorean theorem
a^2 + b^2 = c^2
In other words, sum of the squared smaller lengths are equal to the squared of the longest length
15^2 + 17^2 = c^2
225 + 289 = c^2
c^2 = 514
c = square root of 514
= 22.67156
Round it
Solution: 22.7 km
(10/17) / (-15/17) =
10/17 * - 17/15 =
- 10/15 =
- 2/5 <==
============
2.75 / -2.2 =
- 1.25 <==
============
(-2 3/5) / (3/5) =
- 13/5 * 5/3 =
-13/3 or - 4 1/3 <==
============
(2 1/4) / (3/4) =
9/4 * 4/3 =
9/3 =
3 <==
Y = total costs to get the berries
x = pounds of berries.
bearing in mind that the $5 is just to get in, so is only paid once, whilst the pounds of berry will vary.
Answer: L' is (2,4) M' is (3,1) N' is (0,4)
Step-by-step explanation:
For each ordered pair, you add 2 to the x (the first number, which is horizontal on the graph) and 3 to the y (the second number, which is vertical).
L is (0,1) so you add 2 to the 0 and 3 to the 1 to get L' (2,4)
M is (1,-2), so you add 2 to the 1 and 3 to the -2 to get M' (3,1)
N is (-2,1), so you add 2 to the -2 and 3 to the 1 to get N' (0,4)
