Step-by-step explanation:
In order to know that a graph shows a proportional relationship WITHOUT finding any y/x ratios or doing division, two conditions must be met. Name ONE of the two ways you know a graph is proportional JUST BY LOOKING AT IT. (You will come across another question that asks you to name the other condition, if you haven't already.)

8 – 3(k + 2) = 2 – 3k
Answer:
the answer is 0
Step-by-step explanation:
you distribute the 3 which gives
8 - 3k - 6 = 2 - 3k
then you combine like terms and end up with
2 - 3k = 2 - 3k
then you subtract 2 on each side which gives
- 3k = - 3k
and then when you have to keep combining like terms so you add the 3k on both sides which gives u 0

Answer:
1) Expression
2) Equation
3) Equation
4) Expression
Step-by-step explanation:
An equation always contains an equal sign, so in this case, if it doesn't contain an equal sign, it's an expression.
For 2 and 3, you can see that there is an equal sign, but for 1 and 4, there is not.
Therefore, 1 and 4 are expressions and 2 and 3 are equations.

what is the slope of the line
Answer:
The slope is 1/2.
Step-by-step explanation:
To find the slope of a line, use the equation (y2-y1 / x2-x1)
Let's say (4,3) is x2 and y2. That means (0,-2) is x1 and y1.
(3 - 0) / (4 - -2)
(3 - 0) / (4 + 2)
3/6, which simplifys to 1/2

Answer:
If Kasey bought one drink, she will be able to buy 6 food items
Step-by-step explanation:
We know Kasey has $8 and if she bought one drink, she will have $7.5
We have to find how many food items she can buy (all of them are $1.25)
$7.5/1.25= 6 food items
If Kasey bought one drink, she will be able to buy 6 food items
Hope this helps!
Answer:
6 items
Step-by-step explanation:
8.00 - 0.50 = 7.50
She has $7.50 to spend on food after buying one drink
7.50 ÷ 1.25 = number of food items she can buy
7.50 ÷ 1.25 = 6

One factor of the polynomial 2x3 -3x2 – 3x + 2 is (x - 2), which expression represents the other factor, or factors, of the polynomial?
A. (2x + 1)(x - 1)
B (2.x2 - x+ 1)
C (2x2 + 1)
D. (2x - 1)(x+1)
Answer:
It's actually D (2x - 1)(x+1)
Step-by-step explanation:
The required factor of the polynomial 2x³ - 3x² - 3x + 2 is (2x - 1)(x + 1).
Given that,
One factor of the polynomial 2x3 -3x2 – 3x + 2 is (x - 2), which expression represents the other factor, or factors, of the polynomial is to be determined.
What are the factors?
factors can be defined by splitting the value into multipliable values.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
x - 2 is one factor of 2x³ - 3x² - 3x + 2 than
( 2x³ - 3x² - 3x + 2 ) / x - 2 = 2x² + x -1 = (2x - 1)(x + 1)
Thus, the required factor of the polynomial 2x³ - 3x² - 3x + 2 is (2x - 1)(x + 1).

Tuberia, y cada tubo mide 6 metros de largo. ¿Cuantos tubos se necesitan?
Answer:
n = 641
Step-by-step explanation:
Pipe required to provide water is 3846 m
Length of each pipe is 6 m
We need to find the no of tubes required. Let there are n tubes. It can be calculated as follows :
[tex]n=\dfrac{3846 }{6}\\\\n=641[/tex]

Answer:
Undefined
Step-by-step explanation:
The x value is always 5 so the slope is undefined
Answer:
The slope of the line is undefined.
Step-by-step explanation:
To solve this problem, we should use the formula for slope, which is given below:
m = slope = (y2-y1)/(x2-x1)
If we plug in two of the points that are given in the table, we get:
m = slope = (6-3)/(5-5)
If we perform the subtraction in the parentheses in both the numerator and the denominator, we get:
slope = 3/0
Since we cannot divide by 0, this means the slope is undefined.

It cost $5000 to feed
100 guest at a wedding. It
cost $2750 to feed 45
guests. What is the cost
per plate?
Answer:
Okays so for 100 guests we can make the equation $5000 ÷ 100 = $50.00
For 100 guests at the wedding it would cost $50.00 per plate
For 45 guests we can make the equation $2750 ÷ 45 = $61.111111111111, it would be a repeating decimal
For 45 guests at the wedding, it would cost $61.111111111111
