4. Which of the following can be used
JulsSmile [24]

The option that can be used to support the idea that the set of polynomials is closed under multiplication is; Option C: (10x^(0.5) - 8)(5x^(0.5) + 4)

<h3>What is the Closure property under multiplication?</h3>

When multiplying polynomials, the variables' exponents are added, according to the rules of exponents. It is pertinent to note that the exponents in polynomials are whole numbers. The whole numbers are closed under addition, which guarantees that the new exponents will be whole numbers. Thus, we can also say that the polynomials are closed under multiplication.

Now, looking at the options, we can say that option C is the only polynomial that is closed under multiplication because its' variables and exponents will not change;

(10x^(0.5) - 8)(5x^(0.5) + 4)

The output will retain the same thing.

six times jasons collection of books and one-third of nathans collection add up to 134 books one-third of jasons collection and
atroni [7]
6j + 1/3n = 134...multiply by 3....18j + n = 402
1/3j + n = 31....multiply by 3....j + 3n = 93

the multiplying by 3 is optional...I just did it because it is easier to work with equations when there are no fractions.

18j + n = 402....multiply by -3
j + 3n = 93
----------------
-54j - 3n = - 1206 (result of multiplying by -3)
j + 3n = 93
----------------add
-53j = - 1113
j = -1113/-53
j = 21

j + 3n = 93
21 + 3n = 93
3n = 93 - 21
3n = 72
n = 72/3
n = 24

so Jasons collection (j) consists of 21 books and Nathans collection (n) consists of 24 books

Write in point-slope form the equation of the line that is parallel to the given line and passes through the given point.Your fi
SOVA2 [1]

Answer:

y = x

Step-by-step explanation:

The given equation is

y = x + 5

The slope of this line

m = 1

Since all parallel lines have the same slope, the slope of our line is also m=1.

We now use the point-slope formula

y-y_1=m(x-x_1)

Since the line passes through (-1,-1)

We gave

x_1=-1,y_1=-1

We substitute the slope and point to get

y -  - 1 = 1(x -  - 1)

y + 1 = x + 1

y = x
