In simplifying polynomials, we need to remember that only like terms can be added or subtracted to each other. Also, the order of solving the basic operators should be followed which is PEMDAS.

<span>3x2y2 − 5xy2 − 3x2y2 + 2x2

The first and the thrid term is equal to zero thus the polynomial is:

</span>− 5xy2 <span>+ 2x2
</span>
The polynomial has two terms with a degree of three.

Which box shows a relationship where the constant of proportionality is 64?

Sever21 [200]

Answer:

Step-by-step explanation:

Constant of proportionality = $\frac{y}{x}$

Let's find out which if the boxes will give us 64 as constant of proportionality.

A. $\frac{y}{x} = \frac{11}{2} = 5.5$ ≠ 64

B. $\frac{y}{x} = \frac{5}{15} = \frac{1}{3}$ ≠ 64

C. $\frac{y}{x} = \frac{16}{\frac{1}{4}} = 16*\frac{4}{1} = 64$ ≠ 64

D. $\frac{y}{x} = \frac{\frac{3}{7}}{3} = \frac{3}{7}*\frac{1}{3} = \frac{1}{7}$ ≠ 64

E. $\frac{y}{x} = \frac{2}{-10} = -\frac{1}{5}$ ≠ 64

F. $\frac{y}{x} = \frac{21}{6} = \frac{7}{2}$ ≠ 64

G. $\frac{y}{x} = \frac{4}{8} = \frac{1}{2}$ ≠ 64

From the boxes given, box C is the only box that shows us a relationship where the constant of proportionality is 64.

What’s the an and the a10

malfutka [58]

Answer:

an = -6 + n

a10 = -6+ 10 =4

Step-by-step explanation:

an should start at one behind the first number so it should be -6. Then we add whatever the sequence is increasing by, which is 1 in this case, multiplied by n.

an = -6 + n

a10 = -6+ 10 =4
