Answer:
he bought 20 CDs
Step-by step
25(1.80) equals 45
69-45= 24
24 divided by 1.20 equals 20
Answer:
1).
= (200 -
)
2). Inverse function represents the age of the client and 'x' represents the maximum heart rate of the client.
Step-by-step explanation:
Function representing the maximum heart rate is,
f(x) = 0.85(220 - x)
Here x = age of the client
Equation form of the function will be,
y = 0.85(220 - x)
To get the inverse of the given function, replace 'x' by 'y' and 'y' by 'x' and solve for y.
x = 0.85(220 - y)
220 - y = 
y = 220 - 
Now convert this equation into a function.
= (200 -
)
Here inverse function represents the age of the client and 'x' represents the maximum heart rate of the client.
X - 2 + 9 OVER x + 2.
in other words x - 2 + 9 /x + 2
Answer:
(1, -3)
Step-by-step explanation:
Start where the axes meet. That is the origin (0,)
Move 1 place to the right that is the x coordinate
Move 3 places down that is the y coordinate
(1,-3)
Answer:
Your answer is: x = 2 ± i√14
