It'll be the opposite reciprocal in front of the X like instead of 3 it will be -1/3 so flip it and change the sign
Answer:
irrational number i believe
Step-by-step explanation:
Answer: 16)
(17)
(18)
(19) 3x - 18
<u>Step-by-step explanation:</u>
Inverse is when you swap the x's and y's and then solve for y
16) Given: y = x²
Swapped: x = y²

17) Given: y = 2x + 4
Swapped: x = 2y + 4
x - 4 = 2y

18) Given: y = (x + 2)²
Swapped: x = (y + 2)²
√x = y + 2

19) Given: 
Swapped: 

3(x - 6) = y
3x - 18 = y
Answer:
I believe it would be, 410
explanation:
Inputs are x’s
Substitute the 18 where you see the x
y = 23(18) – 4
y= 414 – 4
y = 410
