Y=-3x+6 y=9 Can anyone please help me with this i need it ASAP

x = -1

Step-by-step explanation:

y=-3x+6

Put y as 9 and solve for x.

9 = -3x + 6

Add 3x and -9 on both sides.

3x = 6 - 9

Subtract.

3x = -3

Divide 3 into both sides.

x = -3/3

x = -1

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.
