Solve the given system of equations.

The solution to the system is ( , ).

x=3

y=1

Step-by-step explanation:

First, get x and y on the left in the lower equation. -2x+10y=4. Then solve using a calculator. Select (apps), PlySmlt2, Simultaneous EQN Solver, and enter your euqations in.

(3, 1)

Step-by-step explanation:

I will show the strategy of elimination in my solution, you can use other strategies but I will use elimination.

Line up variables:

4x - 3y = 9

10y = 2x + 4 -> -2x + 10y = 4

Multiply by 2 for elimination:

-4x + 20y = 8

Now we can add the equations together:

17y = 17

y = 1

Since we know that y is 1, we can plug that into an equation in the system and see what x is.

4x - 3 = 9

4x = 12

x = 3

x = 3

y = 1

Check our

12 - 3 = 9 - Correct

10 = 6 + 4 - Correct

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts
