Polynomials are closed under addition. When subtracting polynomials, the variables and their exponents do not change. Only their coefficients will possibly change. ... Remember that the exponents in polynomials are whole numbers. When adding, distribute the positive (or addition) sign, which does not change any of the signs

Answer:

Polynomials are closed under addition. When subtracting polynomials, the variables and their exponents do not change. Only their coefficients will possibly change. This guarantees that the difference has variables and exponents which are already classified as belonging to polynomials.

lesya692 [45]

The length would be 6 centimeters. You would get this answer because 6 divided by 3 is 2. So you would divide 18 by 3 and get 6. So the length of the second rectangle is 6 centimeters. Hope this helps!
Have a great day!

Jenna and Richie go shopping at the mall to buy their mom a present they buy a scarf for $12.45 and a necklace for $35.65 their

padilas [110]

Answer:

The tax Jenna and Richie pay on the gifts is $3.85.

Step-by-step explanation:

Given:

Cost of scarf = $12.45.

Cost of necklace = $35.65.

State tax charges sale tax = 8%.

Now, to find the sales tax paid on the gifts.

So, adding the price of the gifts:

$12.45+35.65=48.10$

Thus, the total amount of the gifts = $48.10.

Now, getting the sales tax the state charges:

$8\%\ of\ 48.10$

$=\frac{8}{100}\times 48.10$

$=0.08\times 48.10$

$=3.848$

The tax nearest to cent = $3.85

Therefore, the tax Jenna and Richie pay on the gifts is $3.85.

Which graph represents the function f (x) = StartFraction 2 Over x minus 1 EndFraction + 4?

Pepsi [2]

Answer:

On a coordinate plane, a hyperbola is shown. One curve opens up and to the right in quadrant 1, and the other curve opens down and to the left in quadrant 3. A vertical asymptote is at x = 1, and the horizontal asymptote is at y = 4

Step-by-step explanation:

The given function is presented as follows;

$f(x) = \dfrac{2}{x - 1} + 4$

From the given function, we have;

When x = 1, the denominator of the fraction, $\dfrac{2}{x - 1}$ , which is (x - 1) = 0, and the function becomes, $\dfrac{2}{1 - 1} + 4 = \dfrac{2}{0} + 4 = \infty + 4 = \infty$ therefore, the function in undefined at x = 1, and the line x = 1 is a vertical asymptote

Also we have that in the given function, as x increases, the fraction $\dfrac{2}{x - 1}$ tends to 0, therefore as x increases, we have;

$\lim_ {x \to \infty} \dfrac{2}{(x - 1)} \to 0, and \ \dfrac{2}{(x - 1)} + 4 \to 4$

Therefore, as x increases, f(x) → 4, and 4 is a horizontal asymptote of the function, forming a curve that opens up and to the right in quadrant 1

When -∞ < x < 1, we also have that as x becomes more negative, f(x) → 4. When x = 0, $\dfrac{2}{0 - 1} + 4 = 2$ . When x approaches 1 from the left, f(x) tends to -∞, forming a curve that opens down and to the left

Therefore, the correct option is on a coordinate plane, a hyperbola is shown. One curve opens up and to the right in quadrant 1, and the other curve opens down and to the left in quadrant 3. A vertical asymptote is at x = 1, and the horizontal asymptote is at y = 4.
