16 black, 13 blue, 2 red

16+13+2 = 31 total

16/31 is the probability of picking black

13/31 is the probability of picking blue

2/31 is the probability of picking red, so 29/31 is the probability of not picking red (since 31-2 = 29 are not red out of 31 total)

The sum of two numbers is 60 and the difference is 2 what are the numbers.
oksian1 [2.3K]
Let the two numbers be x and y
Then
x + y = 60
And
x - y = 2
x = y + 2
Putting the value of x in the first equation we get
x + y = 60
y + 2 + y= 60
2y + 2 = 60
2y = 60 - 2
2y = 58
y = 58/2
y = 29
Now putting the value of y in the first equation we get
x + y = 60
x + 29 = 60
x = 60 - 29
x = 31
So the value of the two numbers comes out to be 31 and 29. I hope the procedure is clear enough for you to understand.

7. Which property of polynomials says that the sum of two polynomials is also a polynomial?
vlabodo [156]

Answer:

Closure property

Step-by-step explanation:

The closure property of polynomials for addition says that, if we add any two polynomials , the result is also a polynomial.

For is

{x}^{2}  + 2

is a polynomial.

x - 2

is also a polynomial.

The sum of the two polynomials is

{x}^{2}  + 2  + x - 2 =  {x}^{2} + x

The result:

{x}^{2}  + x

is also a polynomial.

velikii [3]
All you have to do is plug in the given x values. your first equations would read:

f(-3) = 2^(-3)
f(-2) = 2^(-2)
f(-1) = 2^(-1)

these can be solved by moving decimal points or entering them into a calculator. regardless of the method, your answers are:

f(-3) = 0.002
f(-2) = 0.02
f(-1) = 0.2

so just repeat that process to fill in the rest of your table. to graph it, you'll use them as normal (x, y) points:

(-3, 0.002)
(-2, 0.02)
(-1, 0.2)

the graph might be a little difficult, working with such small values, but precision isn't totally important--0.002 will be super close to 0, 0.02 will be slightly further, 0.2 will be slightly further. the smaller values don't matter as much graphically and you'll recognize the graph of a growing exponential as you graph more of the table.
