For some number x, we subtract 0.1x and get 171.

So we have:
x-0.1x=171
\rightarrow 0.9x=171
\rightarrow x=190

Identify the property shown. −1.4+(−2.6+3.8)=(−1.4+(−2.6))+3.8
Dimas [21]
<span>This property is called associativity. It shows that it doesn't matter whether you perform the sum on the first two numbers and then the third, or on the second two and then the first, because you will get the same answer either way. That is because addition is associative.</span>

Create a function that has a derivative of f(x) = 2x + 1 at a given input value of your choice.
Taya2010 [7]
The opposite operation to taking a derivative is an integral. Integrate to find original function.

f(x) = x^2 + x + C

C is constant because we didn't have bounds on the integral. it lets you choose the input value let's say is just (1,0)

0 = 1 + 1 + C
- 2 = C

function at input value (1,0)
f(x) = x^2 + x - 2

now if you check by taking derivative is :
f' = 2x + 1
