Solve graphically the system of linear equations: 3x−2y=6 3x+10y=−12

me

The solution of the system of equations is the point

Step-by-step explanation:

we have

-----> equation A

-----> equation B

we know that

The solution of the system of equations is equal to the intersection point both graphs

using a graphing tool

The intersection point is

therefore

The solution of the system of equations is the point

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
