F(x) = (1/2)x + 4
Plug y in for f(x).
y = (1/2)x + 4
Swap x and y.
x = (1/2)y + 4
Solve the equation for y =.
Subtract 4 from both sides.
x - 4 = (1/2)y
Multiply each term 2.
2x - 8 = y
Plug f^-1(x) in for y.
f^-1(x) = 2x - 8

f^-1(4) = 2(4) - 8
f^-1(4) = 0

What number is to 100 as 4 is to 78
vitfil [10]
Hello, 

4 is to 78 as x is to 100, we write it as a ratio:

\frac{4}{78}= \frac{x}{100}   \\  \\ x= \frac{100*4}{78}  \\  \\ \boxed{x= \frac{200}{39}=5.13}

Anton [14]

Answer:

£4867.2

Step-by-step explanation:

Given data

P= £4500

T=2 years

R= 4%

The compound interest expression

A=P(1+r)^t

substitute

A= 4500(1+0.04)^2

A=4500(1.04)^2

A=4500*1.0816

A=£4867.2

Hence the balance is £4867.2

Possible my last brainliest if its right question idk may be more but this one is harsh for me
adelina 88 [10]
Correct Solution: He read 1.5 pages per minute.


Error Analysis: You should’ve divided 3 by 2 not 300. There are 300 pages in the book total. This information is irrelevant to the question. Cole reads 3 pages in two minutes. So you divide 3 by to to find out how many pages he reads per minute. 3/2=1.5
