Answer:
3
Step-by-step explanation:
5% is converted into the decimal form 0.05. To find 5% of the 60 dogs which are pure bred, multiply 60*0.05 = 3. This means 3 are purebred.
Answer:
Linear
Step-by-step explanation:
As x increases by 1, f(x) decreases at a constant rate of -5.
Since the rate is constant, the function must be linear.
<u>Given </u><u>:</u><u>-</u>
- A function f(x) = - (x -17)/12
<u>To </u><u>Find</u><u> </u><u>:</u><u>-</u>
- The inverse of the function .
<u>Solution</u><u> </u><u>:</u><u>-</u>
The given function is ,
f(x) = -(x-17)/12
Replace y with f(x) ,
y = -(x-17)/12
Interchange x and y ,
x = -(y-17)/12
Solve for y ,
12x = -y +17
y = -12x +17
Replace y with f-¹(x) ,
![\longrightarrow\sf \ f^{-1}(x)= -12x +17](https://tex.z-dn.net/?f=%5Clongrightarrow%5Csf%20%5C%20f%5E%7B-1%7D%28x%29%3D%20-12x%20%2B17)
<u>Hence </u><u>the</u><u> required</u><u> answer</u><u> is</u><u> </u><u>-12x </u><u>+</u><u>1</u><u>7</u><u>.</u>
