Answer:
x=3, z=-1, y=6
Step-by-step explanation:
you need to make the coefficients of each variable equal to each other then subtract 2 equations.
this one: multiply -4 in 1st
4x+4y+4z=32
-4x+4y+5z=7
_____________
8x+0-z=25
we have 2 equations with 2 variables now
2x+2z=4
8x-z=25
It will be a horizontal line at y=7 and shaded above. If you have pictures of the graph I can show which one it would be.
Answer:
k = 11
Step-by-step explanation:
let the points be A(-2,5), B(2,8), C(6,K).
for the points to be collinear slope of line AB maust be equal to line BC.
slope of line AB = 
slope of line BC = 
therefore 
therefore k = 8 + 3
k = 11
Answer:
The median are equal
Step-by-step explanation:
Given
I will answer this question with the attached plot (see attachment 2)
Required
The equal statistical measures
See attachment 1 on how to read a box plot
Using attachment 1 as a guide, we have the following observation
<u>Movie 2</u> <u>Movie 1</u>




By comparison, they have equal median (30)
-6 is a rational I believe
