Answer:
Gregory gets 4 coffee for free and the total number of coffee he gets is 16.
Step-by-step explanation:
Given that when customers pay for 3 coffees, they get another coffee free.
So, for the cost of 3 coffee, 1 coffee is free.
Therefore, for the cost of 3n coffee, n coffee is free.
As Gregory pays for 12=3x4 coffees, the number of free coffee, n=4.
So, the total number of coffee Gregory = 12+4=16.
Hence, Gregory gets 4 coffee for free and the total number of coffee he gets is 16.
|PR| = |PQ| + |QR|; |PQ| = |QR| conclusion |PR| = 2|PQ|
|PQ| = 3y; |PR| = 42; |QR|=?
subtitute
42 = 2(3y)
6y = 42 |divide both sides by 6
y = 7
|QR| = 3(7) = 21
I'm not sure if this is referring to a specific question or not, but in general turtles are faster than tortoises
Answer:
first option
Step-by-step explanation:
Given
y = 2(x - 3)² + 1
Rearrange making x the subject
Subtract 1 from both sides
y - 1 = 2(x - 3)² ( divide both sides by 2 )
= (x - 3)² ( take the square root of both sides )
± = x - 3 ( add 3 to both sides )
± + 3 = x
Change y into terms of x with x being the inverse, that is
(x) = ± + 3
