Determine whether the following statement is true or false and then explain with an example: "Due to a downturn in the economy,
Musya8 [376]
Of course, this statement is FALSE.
Let`s assume that a small town in Nevada had a population of 1,000.
When it lost 20% of its population:
1,000 * ( 1 - 0.2 ) = 1,000 - 0.8 = 800 
After that the same town gained 20 % more people:
800 * ( 1 + 0.2 ) = 800 * 1.2 = 960
960 ≠ 1,000
In the end the town`s population was not the same as it was before the downturm.

What are the missing angles?
iVinArrow [24]

Answer:

if ∠1 = 34°

then:

∠2 = 180 - 34 = 146° because it is supplementary to ∠1  (supplementary angles total 180°)

∠3 = 146° because it is a vertical angle of ∠2

∠4 = 34° because it is a vertical angle of ∠1

Tell whether the given ordered pair is a solution of the equation y = -2 + 5;(2,1)
Kamila [148]

<em>Note: your equation is a little bit unclear. Thus, I am assuming that </em>

<em>y = 2x+5</em>

<em> Anyway, the procedure remains the same. It would anyways clear your concept.</em>

Answer:

We conclude that the ordered pair (2, 1) is a solution.

Step-by-step explanation:

Given the equation

y = -2x+5

Check for point (2, 1)

substituting the point (2, 1) in the equation to check whether the ordered point satisfies the equation or not.

y = -2x+5

plug in x = 2 and y = 1

1 = -2(2)+5

1 = -4+5

1 = 1

R.H.S = L.H.S

TRUE

Therefore, the given ordered pairs satisifes the equation.

Hence, we conclude that the ordered pair (2, 1) is a solution.
