Answer:

Step-by-step explanation:
Given function,

Step 1 : Replace g(x) by y:

Step 2 : Swap x and y:

Step 3 : Solve the equation for y ( isolate y in the left side ):





Step 4: Replace y by
:

Hence, the inverse of the function g(x) is
.
Answer:
Brand x: 80
Brand y: 45
Step-by-step explanation:
x + y = 125
20x + 15y = 2275
-20x - 20y = -2500
(+) 20x + 15y = 2275
--------------------------------
-5y = -225
y = 45
x + y = 125
x + 45 = 125
x = 80
Answer:
Brand x: 80
Brand y: 45
Answer:
8
Step-by-step explanation:
0.3{10} + 10 / 2
3 + 10/2
3 + 5
8
6*2 = 12
12/2 = 6
So, the answer could be 12/2
