Answer:
(59) = 20
Step-by-step explanation:
(x) is the inverse of f(x)
to find the inverse function, let f(x) = y and rearrange to make x the subject.
y = 3x - 1 ( add 1 to both sides )
y + 1 = 3x ( divide both sides by 3 )
= x
change y back into terms of x with x =
(x) , then
(x) =
, then
(59) =
=
= 20
Answer:
20% increase
Step-by-step explanation:
Initial price: $2.25
New price: $2.70
Percentage=(new price - initial price)×100/(initial price)
p=(2.70-2.25)×100/2.25=45/2.25=20%
Area of garden = 81 ft²
Area of square = side²

Perimeter of square = 4 × Side
= 4 × 9
= 36 ft
Fencing needed by Janet = 36 ft
Adult ticket= $6.00 Child ticket= $3.00
Total=$168.00
$6 x 17 people=$102 $3.00 x 17 kids= $51 + 5 kids x$3=$168
Adult tickets sold= 17
Children's Tickets sold= 22
The answer
is 11 if you divide 176 by 16 it = 11
