Answer:
<h2>
h(x) = 4x+48</h2>
Step-by-step explanation:
Given the function f(x) = 1/4x -12. To get the inverse of the function, first we will let y = f(x) to have y = 1/4x - 12.
Then we will make x the subject of the formula as shown:
y = 1/4x - 12
adding 12 to both sides we have;
y + 12= 1/4x - 12 + 12
y + 12 = 1/4x
Multiplying both sides by 4 we have;
4(y+12) = x
x = 4y + 48
Substituting y for x
y = 4x+48
f^-1(x) = 4x+48
h(x) = 4x+48
Thee final expression will give the inverse of the function
Answer:
Hallie ride 62 miles on bicycle.
Step-by-step explanation:
Given:
Let the number of miles Samantha rode be 'x'.
Hallie rode her bicycle 7 miles less than 3 times the number of miles Samantha rode.
It means that number of miles Hallie ride is equal to 3 multiplied by number of miles Samantha rode and then subtracting by 7.
framing in equation form we get;
number of miles Hallie ride =
But Given:
number of miles Samantha rode =23 miles.
Now by substituting the value of in above equation we get;
number of miles Hallie ride =
Hence Hallie ride 62 miles on bicycle.
