explain why 2+x and x+3 are equivalent
Check whether the two expressions 2x+3y2x+3y and 2y+3x2y+3x equivalent.
The first expression is the sum of 2x2x 's and 3y3y 's whereas the second one is the sum of 3x3x 's and 2y2y 's.
Let us evaluate the expressions for some values of xx and yy . Take x=0x=0 and y=1y=1 .
2(0)+3(1)=0+3=32(1)+3(0)=2+0=22(0)+3(1)=0+3=32(1)+3(0)=2+0=2
So, there is at least one pair of values of the variables for which the two expressions are not the same.

Answer:
Perimeter = 25
Step-by-step explanation:
J(-2, 5)
K(1, 1)
L(1, -1)
M(-5, -4)
N(-5, 1)
Formula for distance between 2 coordinates is;
d = √((x_2 - x_1)² + (y_2 - y_1)²)
Thus;
JK = √((1 - (-2))² + (1 - 5)²)
JK = √25
JK = 5
KL = √((1 - 1)² + (-4 - 1)²)
KL = √25
KL = 5
LM = √((-5 - (-1))² + (-4 - (-1))²)
LM = 5
MN = √((-5 - (-5))² + (1 - (-4))²)
MN = 5
JN = √((-5 - (-2))² + (1 - 5))²)
JN = 5
Thus;
Perimeter = 5 + 5 + 5 + 5 + 5
Perimeter = 25
Which expression is not equal to the expression shown?
Answer:
[tex]3^{-3}[/tex] ÷ [tex]3^{4}[/tex]
Step-by-step explanation:
When pulged into a calculator:
[tex]3^{3}[/tex] ÷ [tex]3^{-4}[/tex] = 2187
When your options are pulged in you get this:
[tex]3^{-3}[/tex] ÷ [tex]3^{4}[/tex] = [tex]\frac{1}{2187}[/tex]
[tex]3^{3}[/tex] · [tex]3^{4}[/tex] = 2187
[tex]3^{7}[/tex] ÷ [tex]3^0[/tex] = 2187
3 · [tex]3^6[/tex] = 2187
because [tex]3^{-3}[/tex] ÷ [tex]3^{4}[/tex] doesn't equal 2187 that is your answer.

What is the slope of a line that passes through the points open parentheses short dash 1 comma 9 close parentheses and open parentheses 3 comma 6 close parentheses? a.) 10 over 3 b.) 3 over 10 c.) short dash 3 over 4 d.) short dash 4 over 3
Answer:
-3/4
Step-by-step explanation:
The answer will be option c which is short dash 3 over 4.
What is the slope?Slope or the gradient is the number or the ratio which determines the direction or the steepness of the line.
Given points are:(1,9) and (3,6)
The slope of the line will be calculated as:-
y = mx + c
9 = m+c
6 = 3m+c
By solving the above linear equations we will get the value of m which will be our slope.
m = -3/2
Hence the answer will be option c which is short dash 3 over 4.

Answer:
3(x^3)y -6x(y^2) +93Step-by-step explanation:
The above-listed answer choices are the only ones that are self-consistent.
The quotient choices all have a leading coefficient of 3, and the result of dividing by <some number> is a leading coefficient of 1. Obviously, the <some number> must be 3 (first choice on the second menu).
Looking only at the constant term, we see that after division by 3, we have 3. So the original quotient constant term must be 3×3 = 9 (first choice on the first menu). Note that we have chosen the correct answer simply by looking at coefficients, not even bothering with actual division of variables.

Okay so, first put a dot on the number three. Next, go down one and over two from that spot (2, 2) and so on.
Step-by-step explanation:
Answer and step-by-step explanation:
Here, we are given a linear equation, meaning that the graph is going to be a straight line. Firstly, we must identify the slope and the y-intercept of the line.
y = -1/2x + 3
The -1/2x is our slope, and the 3 is our y-intercept. So, let's plot the coordinate (0, 3) because that is the y-intercept. Lastly, we must find how steep the line is, and what direction it goes to. As you can see, it is negative, so that means that the slope will go from the top left to the bottom right. And, the slope is -1/2, which means that for every time you go to right two, you will also go down one. Hope this helps!

In the Michigan State Lottery, a player wins the grand prize by correctly picking 6 different numbers
from 1 to 49. The numbers do not need to be selected in order. If a player buys one ticket, find the prob-
ability of winning the grand prize.
Answer:
e
Step-by-step explanation:
use a calculator online
The probability of winning the grand prize is 0.00101 if the In the Michigan State Lottery, a player wins the grand prize by correctly picking 6 different numbers from 1 to 49.
What is probability?It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
We have a player wins the grand prize by correctly picking 6 different numbers from 1 to 49.
Total outcome = C(49, 6) (repetition not allowed)
= 13983816
Favourable outcomes = 49⁶
Probability of winning the grand prize:
= 13983816/49⁶
After calculating:
P = 0.00101
Thus, the probability of winning the grand prize is 0.00101 if the In the Michigan State Lottery, a player wins the grand prize by correctly picking 6 different numbers from 1 to 49.

Find the length of side x in simplest radical form with a rational denominator.
60°
V3
30°
X
Answer:
4√3/3
Step-by-step explanation:
Find the diagram attached below
Considering angle 60°
Opposite side = 2
Hypotenuse = x
Using the SOH CAH TOA identity
sin theta = opposite/hypotenuse
sin 60 = 2/x
x = 2/sin60
x = 2/(√3/2)
x = 2 * 2/√3
x = 4/√3
Rationalize
x = 4/√3 * √3/√3
x = 4√3/3
Hence the value of x in its simplest form is x = 4√3/3
