2 answers:

7 0

You are solving for the variable. Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS:

8) z- 4 = -8

Isolate the z. Add 4 to each side

z - 4 (+4) = -8 (+4)

z = -8 + 4

z = -4

C. z = -4 is your answer

----------------------------------------------------------------------------------------------------------------

9) -3 = x/5

Note the equal sign. What you do to one side, you do to the other. Isolate the x. Multiply 5 to both sides

-3(5) = x/5(5)

x = -3(5)

x = - 15

B. x = - 15 is your answer

P(3) = 1/6
P(odd) = 3/6 = 1/2 ........(odd = 1,3,5)
P(less than 5) = 4/6 = 2/3.....(less than 5: 1,2,3,4)
P(prime) = 3/6 = 1/2 ..........(prime: 2,3,5)
P(4 or 6) = 2/6 = 1/3
P(not 1) = 5/6 .....................(not 1: 2,3,4,5,6)

hope it helps

How do you Identify and contrast the differences between the rise in prices due to inflation and the rise in prices in microecon

andrezito [222]

One can Identify the differences between the rise in prices due to inflation and the rise in prices in microeconomic markets by?

Observing the trends in prices.
Observing Demand and supply curve.

<h3>Contrast the differences between the rise in prices due to inflation and the rise in prices in microeconomic markets.</h3>

The difference that exist between a rise in price due to the inflation and a rise in price due to microeconomic markets is based on the price changes that has occurred in terms of demand and supply model.

Note that this is said to be the price in a given market but the price rise as a result of to inflation tells that the price rise is one that reaches a lot of markets and not only just one market.

Hence, One can Identify the differences between the rise in prices due to inflation and the rise in prices in microeconomic markets by?

Observing the trends in prices.
Observing Demand and supply curve.

Factor completely

Answer:

Step-by-step explanation:

1. $7x^3y+14x^2y^3-7x^2y^2$

The GCF of all the term of the above polynomial is $7x^2y$ , hence we take it outside and form a bracket

$7x^2y(x+2y^2-y)$

The polynomial within the bracket can not be factorized further hence this is our final answer. Option (B) is the right answer

2. $5x(x+3)+6(x+3)$

The GCF of all the term of the above polynomial is $(x+3)$ , hence we take it outside and form a bracket

$(x+3)(5x+6)$

The polynomial within the bracket can not be factorized further hence this is our final answer. Option (B) is the right answer

3. $8x^5+2x^4+4x^2$

The GCF of all the term of the above polynomial is $2x^2$ , hence we take it outside and form a bracket

$2x^2(4x^3+x^2+2)$

The polynomial within the bracket can not be factorized further hence this is our final answer. Option (D) is the right answer
