Answer: Which statement is False
Step-by-step explanation:
proportional relationships
y ∝ x
=> y = kx
Comparing with line line of equation
y = mx + c
m = k , c = 0
Hence A proportional relationship must graph as a line
TRUE
at x = 0 , y = 0
Hence graph of a proportional relationship must pass through (0, 0).
TRUE
y = kx
=> y/x = k hence
Each point (or pair) in a proportional relationship must share the same ratio.
TRUE
Each point (or pair) in a proportional relationship must share the same difference.
FALSE
Answer:
8
Step-by-step explanation:
First do whats in the parenthesis:
(8+18/9)
Using PEMDAS again, we do the division first:
(8+2)
Now addition:
(10)
Now subtraction:
(10)-2
8
170 ≤ 75 + 12.5v (third one)
We are given 4 points.




Using this, we can make an equation.

I got
by using the slope formula.



So the equation we have is 
Now, we can solve for how much peanut butter is used to make 25 packages by plugging in 25 for
, which is the number of cracker packages.


We need to use
teaspoons of peanut butter to make 25 packages of crackers.
Hope this helps.
頑張って!
Answer:

Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
Let
x -----> the number of minutes
y ----> the water level in centimeters
In this problem we have a proportional relationship between the variables x and y
Find the value of k
For x=6 min, y=11 cm
-----> the slope is equal to the constant of proportionality k
The linear equation is

so
For (12,y)
we have
x=12 min
substitute in the equation and solve for y
