How would you simplify this -5x+2x+7y-3x
forsale [732]
In these types of problems, the first step is to combine like terms. Like terms are terms with the same exponent (power), and the same variable (like all x's). In the above equation, we can combine -5x, 2x and -3y. Let's do it:
-5x+2x+7y-3y = -6x+7y

The next step would be to factor out the common ratio, which is not applicable here, so your answer would be -6x + 7y. Hope this helps!

labwork [276]

Answer:

1, 2, 2, 2, 3, 8, 9

Step-by-step explanation:

The following data represent the times in minutes required for 18 co-workers to commute to work

48 42 31 29 41 22 38 38 21 39 22 48 22 12 34 32 23 28

Rewrite this data in ascending order

12 21 22 22 22 23 28 29 31 32 34 38 38 39 41 42 48 48    

Now, the stem-and-leaf plot is

\begin{array}{cc}\text{Stem}&\text{Leaf}\\ \\1&2\\2&1,2,2,2,3,8,9\\3&1,2,4,8,8,9\\4&1,2,8,8\end{array}

The second row represents the leaves for the given data points in the range 20 to 29 for this stem-and-leaf plot, so the answer is

1, 2, 2, 2, 3, 8, 9
