Step-by-step explanation: What they mean is if you were to say put all that data onto a graph, any kind of graph. What graph would you chose, and why? How you would work through this kind of problem, or at least how I would approach it weight out the pros and cons of each graph, or put some data on different graphs and see what works best. On the contrary if you have a rough idea of how each graph would look like you would just chose the one you think conveys the information best. I think they're is a best answer, but no wrong answer, you can make an argument for most graphs if you try, so just chose the one you think is best, and write your reasoning.
Answer:
Equation: -6n-2n=16
Combine like terms: -8n=16
Divide by -8 on both sides: n=-2
Let me know if this helps!
Answer: The equation that describes proportional relationship is y = 0.75x
Constant of proportionality is 0.75
Step-by-step explanation:
4y = 3x
Divide both sides by 4 to get the value of y
y = 3x/4
12y = 9x
Divide both sides by 12 to get the value of y
y = 9x/12 divide the numerator and denominator by a common value of 3
y= 3x/4
y = 0.75x
The equation that describes proportional relationship is y = 0.75x, meaning y is inversely proportional to x, as x increases, y also increases.
Constant of proportionality is 0.75

0.29 as a fraction in simplest form is 29/100
45km : 30 min = 180km : x
x = 
= 
= 60*2 min = 120 min = 2h
