If f(x) = 0.8(2 – x), what is the value of f(–2)?
Sergio039 [100]
With functions, you take the number that is in the ( ), so we have f(-2), and take the fomula f(x) = 0.8(2 – x) and everywhere you see an 'x' replace it with the -2 f(–2)=0.8(2 – (-2)) 

We will have to work with the expression of 0.8(2-(-2) When you want to evaluate these types of expressions, you want to use the Order of Operations: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. First we have to evaluate the parentheses. What is 2-(-2)
 its 4.

ok now you got 0.8 (4)

 Now we have the remains of 0.8(4). If a number is within the parenthesis, then it means that we have to multiply the number inside with the number that is outside. What is 0.8*4 its 3.2 soooo your answer is going to be

3.2

Choose all the units that are part of the metric system ?
KatRina [158]

Answer:

The metric system is a system of measurement that uses the meter, liter, and gram as base units of length (distance), capacity (volume), and weight (mass)

Step-by-step explanation:

The metric system uses units such as meter, liter, and gram to measure length, liquid volume, and mass, just as the U.S. customary system uses feet, quarts, and ounces to measure these.

In addition to the difference in the basic units, the metric system is based on 10s, and different measures for length include kilometer, meter, decimeter, centimeter, and millimeter. Notice that the word “meter” is part of all of these units.

Choose the numbers that are irrational.
ddd [48]
As the numbers are written, none of them are irrational because they are all terminating decimals:

3.624=\dfrac{3624}{1000}=\dfrac{453}{125}
0.6=\dfrac6{10}=\dfrac35
0.87=\dfrac{87}{100}
-5=-\dfrac51

Perhaps there is some missing notation in your question?
