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

Which of the following situations represents choosing a random sample? Assign each person of the population a number. Put all th
Nina [5.8K]
Answer: The first and second options are random samples.

First, assign numbers and drawing the number from a bowl would be a great way to get a random sample. Everyone has the same chance of being selected.

Second, using an alphabetical order is just like the first choice. The chances are the same for everyone.

However, in the third choice, you won't get a random sample. You will get an old and young group. Not a random group of the population.

Help please and thank u​

Answer:

The line is y = (1/2)x + 3

Step-by-step explanation:

We can calculate a slope.  I'll use the two points (-4,1) and (-1,2.5).

Rise = (2.5-1) = 1.5

Run = (-1-(-4)) = 3

Rise/Run = Slope = (1.5/3.0) = 1/2

Find b, the y-intercept, by using point (-4,1) in the equation y = (1/2)x + b

y = (1/2)x + b

1 = (1/2)*(-4) + b

1 = -2 + b

b=3

The line is y = (1/2)x + 3

If Mp =5x - 34 and 2x -4 Find MP
Aliun [14]

Answer:

Mp=24

Step-by-step explanation:

From expression 2x-4, we solve for x.

Then we have: x=4/2 → x=2

Replace x=2 in Mp=5x-34

Solve for Mp:

Mp=5x2-34

Mp=10-34

Mp=-24
