Answer:
Step-by-step explanation:
6x=120-5y -> x=20-5/6*y -> 7(20-5/6*y) + 11y =202 -> 140-35/6*y + 11y = 202 -> 140+31/6*y=202 -> 31/6*y = 62 -> y = 12.
Answer: Positive
Step-by-step explanation:
A scatter plot for speed and distance is created.
We know that distance = speed x time
Hence when speed increases , distance increases and similarly when speed decreases, distance decreases.
Thus if we plot on x axis distance, we find that x increases when y increases.
So we find that there is a strong positive relationship between the two variable
D=tS
where D= distance S=speed and T=time.
Since D varies directly as speed, we have positive relationship.
Hope this helps! :)

Answer:
see attached
Step-by-step explanation:
a) A system of equations has no solutions when the graphs of those equations do not intersect. If the equations are equations of a line, then the lines must be parallel in order for them not to intersect.
Any parallel line will do.
__
b) There is one solution when the graphs intersect in exactly one point.
Any line that crosses the one shown will do.
__
c) There are infinite solutions when the graphs describe the same curve.
A line overlapping the one shown is the one you want.
