Solve the following system of equations
{y=1/6x+8
{y=3/4x+1 NEED HELP ASAP

x = 12 and y = 10

Solution:

Given system of equations are

– – – – (1)

– – – – (2)

Both are equations of y.

So, we can equate both the equations.

Arrange like terms one sides.

Take LCM of the denominators.

LCM of 6 and 4 = 12

Make the denominators same.

Divide both side of the equation by –7, we get

x = 12

Substitute x = 12 in equation (1).

y = 10

Hence x = 12 and y = 10.      

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.
