PLS HELP 50 POINTS! WILL GIVE BRAINLIEST 2x2 = 200

Method Selected:
Your Work:

Divide both sides by 2 and apply square root (both sides).

Step-by-step explanation:

Hi, to answer this question we have to analyze the expression given:

2x²=200

A more simple way to solve the expression:

First, we have to divide each side by 2:

2x²/2=200/2

x²=100

Square root on both sides:

√x²=√100

x = -10 and 10

{-10;10}

Feel free to ask for more if needed or if you did not understand something.

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.

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
