Compound interest earned would be $1.1034

Step-by-step explanation:

The formula for amount, when interest is compounded annually is

A = P(1+r)^n

Here

A= amount

P= principal

r= rate of interest

n= time period

So putting the values in the formula

A = 7(1+.05)^3

A = 7*(1.05)^3

A = 7*1.157625

A= 8.1034

So the Compound Interest would be

C.I = 8.1034-7.0

C.I = 1.1034

If u subtract 17 from my number and multiply the difference by -7, the result is -35.What is my number

Kryger [21]

Let x = your number.

(x - 17) * -7 = -35. Divide each side by -7.

(x - 17) = 5. Add 17 to each side.

x = 22.

Your number is 22

Convert 11.42424242 to a rational expression in the form of a/b , where b ≠ 0.

11.424242
isolate the repeating part
11+0.424242

focus on the repeating part
0.42424242
how many places till it repeats again?
2
let's say it is x
x=0.42424242
multiply by 100
100x=42.424242

subtract them
100x-x=42.42424242-0.42424242
the infinite repeats cancel and we get
99x=42
divide by 99
$x=\frac{42}{99}$

so
$11.\overline{42}=11 \space\ \frac{42}{99}$

It's linear

If you evaluate x when it's 0 you'll get the cut in y, that means the function will pass on (0,7)

The formula for linear functions is y=mx +b

In this case b is 7

M=7-5/0+1

M=2

Now you just write the function down, it would be
