<span>If (x, 7√3) is a point on the unit circle, then x2 + (7√3)2 = 1 and </span>-1 ≤ x ≤ 1. <span>So, x2 = 1- (7√3)2 = 1- 147 = -146</span> <span>Since there is no value of x where -1 ≤ x ≤ 1 and x2 = -146, the given point is NOT on the unit circle.

Answer:
7x = 2x + 50
Step-by-step explanation:
Let the number be x.
Seven times the number = 7x
Two times the number = 2x
But from the question,
7 times the number is equal to 50 more than twice the number. This is illustrated below:
7x = 2x + 50
Answer:
3
Step-by-step explanation:
one whole divided by one-third is written as....
1 ÷ 1/3
Use KFC to simplify
Keep the first fraction or number, Flip the second fraction, and change it to multiplication...
so we have 1 * 3/1 which is 3/1 or just 3
* you can also read this as, how many thirds go into 1. 3 thirds will go into 1
