What math function and made i can help
For this case we must simplify the following expression:

To do this, we convert the mixed numbers to improper fractions:

Answer:

Answer:
Step-by-step explanation:
Move the decimal to the left once on both of them and time the numbers together
First we need to find the slope of line k. Using the slope formula, we fill in accordingly:

. The slope is -3/2. The slope of a line that is perpendicular to line k will have the opposite sign (so, positive) and will be the reciprocal of the line k's slope (so, 2/3). You could also say, more "mathematically legal", that the product of the slopes of perpendicular lines is -1, but it's easier to just say that they are opposite reciprocals. The slope you're looking for is 2/3. Choice 3 above.
-1/4 + (-5/3)
When there is no number between a grouping symbol and a + or - sign, by default you can multiply the contents in the group by 1 to get rid of the grouping symbols.
