I did some research, and I think it's the first one. PLEASE CORRECT ME IF I'M WRONG!!
Here's why, because the first segment extends from 0 to 1. So, x has to be 0 or larger, but less than 1 or 1.
Subtract 153-63=90 and I am pretty sure that's what you have to do
19. (X+5)-3
20. 2a
21.3b
22. 5y-5
23. 1/2n-15
Step-by-step explanation:
because the total sum of each percent is 90%
and it must be 100% as it is a full circle
Answer:
no
Step-by-step explanation:
We can use the Pythagorean theorem to check
a^2 +b^2 = c^2
11^2+13^2 = 17^2
121+169 =289
410 does not equal 289
This is not a right triangle
