How to add and subtract mixed numbers

First, you would convert the mixed numbers into fractions by multiplying the denominator by the whole part (the number to the left of it) and by adding that number by the numerator. After that, you would check if the fractions have the same denominator. If they do, just add/subtract them by adding/subtracting their numerators together (leave the denominator the same). If they don't have the same denominators, then you would have to get a common denominator by multiplying both of the denominators together. Then, once you have that, you multiply your numerator and denominator by whichever number gets you to the common denominator. For example, if you were adding 1/3 and 1/2 together, the common denominator would be 6 (3 times 2). You would then multiply 1 and 3 by 2 (since 3 times 2 is 6) and 1 and 2 by 3 (since 2 times 3 is 6), leaving you with 2/6 + 3/6. Finally, you would add them together, giving you 5/6. I hope this helped and make sure to make this the brainliest answer.

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

answer: the function g(x) has the greatest slope.
