Hello from MrBillDoesMath!
Answer:
x >=4
Discussion:
The inverse of q is
-1 +\- (x-4)^(1/4) (the fourth root of x-4)
(Inverse found by solving x= (y+1)^4 +4 for y)
The domain of the inverse is therefore x such that x -4 >=0 , i.e. x >=4

P.S. I'll be on vacation from Friday, Dec 22 to Jan 2, 2019. Have a Great New Year!
Y x 30% = 24
Y = 24 x 100/30
Y = 80
Total candy bars = 80
Hope this helps.
Answer:
Step-by-step explanation:
hello :
(5y + 6)2 = 24 means : 5y+6 = √24 or 5y+6 = - √24
5y = - 6+√24 or : 5y = - 6-√24
y = (- 6+√24)/5 or y = (- 6-√24)/5
Answer:
$1 or $1.25

(1) a = 16 , (2) x =4 , (3) x = 0 ,(4) n =-20 , (5) r = 20 and (6) x = -11
Step-by-step explanation:
(1) 6 = a/4 + 2
4 = a/4 (It is because when you bring +2 over to the left it will become 6 -2)
a = 16 (it is because of the fraction, so when you bring the divisor over it becomes x 4)
The following questions same as qns 1 too
(2) -6 + x/4 = -5
x/4 = 1
x = 4
(3) 9x -7 = -7
9x = 0
x = 0
(4) 0 = 4 + n/5
-4 = n/5
n = -20
(5) -4 = r/20 -5
1 = r/20
20 = r
(6) -1 = 5 + x/6
-6 = 5 + x
-11 = x
