You can drop the parentheses around 4 - 5y.  (4 - 5y) is the same as 4 - 5y.

But you must expand (multiply out) -2(3.5y - 8).  The result is
        -7y + 16      Here we are applying the Distributive Property of                                                  Multiplication.

Now combine 4 - 5y and - 7y + 16.  Result:   -12y + 20 (answer)

If you need clarification here, please ask!

(4 - 5y) - 2(3.5y - 8)

first distribute

(4- 5y) - 7y + 16

Then simplify
-12y + 20

Then simplify

4(-3y + 5)

hope this helps

The data shown on the scatter plot below demonstrates the relationship between the time of day and the total number
viva [34]

Answer:

Good question! The correct answer is a) increases and b) increases.

While the pair of answers a) decreases and b) decreases or the pair a) stays the same and b) stays the same would be technically correct answers, this is the best way of describing the trend of the scatter plot; typically, trends are described by how the dependent or y-variable responds to the independent or x-variable increasing.

Find the midpoint of the segment with the following endpoints. (10, 7) and (5, 4)
KatRina [158]

Answer:

\frac{15}{2} , \frac{11}{2}

Step-by-step explanation:-

To find the midpoint, the equation we use is:-

\frac{x1 +x2}{2} , \frac{y1 + y2}{2}

x1 = 10

x2 = 5

y1 = 7

y2 = 4

Substituting the values in the equation, we get:-

\frac{10+5}{2} , \frac{7+4}{2}

Coordinates of the midpoint---> \frac{15}{2} , \frac{11}{2}
