Which is the correct solution and graph for x + 1 < 5?

I think that the answer is X<4

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
