Mathematics

Answer:

Step-by-step explanation:

This question is about the benefits of estimation.

1300/13 is easy and results in 100.

1287/13 can be approximated by 1300/13:  1287/13 ≈ 100.

Actually, 1287 = 1300 - 13 = 13(99); just subtract 1 from 100.  

So:  1287/13 = 1300 - 13 = 1287.  A nice bit of mental math!

Which input value produces the same output value for the two functions on the graph?
GrogVix [38]

Answer:

The image of both graphs can be seen below:

Both functions will have the same output for an input x₀ if:

f(x₀) = g(x₀)

This means that, for that particular value of x₀, the functions will intersect each other.

So we just need to look at the graph and find the x-value where the functions intersect. (Remember that the x-values are in the horizontal axis)

We can see that it happens at x = 1.

Then the input value that produces the same output value for the two functions is:

x = 1
