Which algebraic expressions are polynomials? Check all that apply. PLEASE HELP

dexar [7]

Selections 2, 3, 5, 6 are polynomials.

1 and 4 are not. The coefficients don't have to be integers, but the powers of the variables need to be positive integers. In 1, you have x^-1. in 4, you have x^(1/2).

PLEASEEEEEEEE HELP

Rama09 [41]

Answer:

Using the point-slope form:

The equation of the line is given by:

$y-y_1 =m(x-x_1)$ .....[1] where

m is the slope of the line and $(x_1, y_1)$ is the point on the line.

As per the statement:

Given: Two points i,e (34, 76) and (42, 91)

First calculate slope(m):

Slope is given by:

$\text{Slope} = \frac{y_2-y_1}{x_2-x_1}$

Substitute the given values we have;

$\text{Slope (m)} = \frac{91-76}{42-34}=\frac{15}{8}=1.875$

Now, substitute the value of m and (34, 76) in [1] we have;

$y-76 =1.875(x-34)$

Using distributive property: $a \cdot (b+c) = a\cdot b+ a\cdot c$

$y-76 =1.875x-63.75$

Add 76 to both sides we get;

$y=1.875x+76$

Therefore, the equation of the trend line is: $y=1.875x+76$

A student ID number is a letter of the alphabet followed by 2 digits. How many different IDs are possible if the digits can be r

mars1129 [50]

First, there are 26 distinct alphabets and 10 distinct digit numbers.

Then, the first digit of ID has 26 possibilities.

For the rest of 2 digits, the total cases are 10*10 = 100 possibilities.

However, there are 10 cases are repeated when two digits are the same. so you have to subtract it by 10

So answer will be 26 * (100-10) = 23400
