Answer:
i believe it is x=4
Step-by-step explanation:
10x+7=12x-1
7=12x−1−10x
8=2x
divide
x=4
Answer:
dunno do you know the answr??
Step-by-step explanation:
Answer:
see the explanation
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 time in seconds
y ---> the distance in meters
In this problem we have a proportional relationship between the variables x and y
Find the constant of proportionality k

For x=2, y=25 ---> 
For x=4, y=50 ---> 
For x=6, y=75 ---> 
For x=8, y=100 ---> 
so
The value of k is 
In this problem the value of k or slope represent the speed of the train
The linear equation is equal to
or
Answer:
$44 per 1 meal
Step-by-step explanation:
They are the same because they have the same slope but are different because they have different y intercepts.
