x=2, y=3 is a pair of a equations right there, so a correct solution.
How about another linear system?
Answer: x+y=5, 10x + y = 23
[tex]\mu[\tex]=8
[tex]\sigma[\tex]=0.7
x=9
Z=(x-[tex]\mu[\tex])/[tex]\sigma[\tex]
=(9-8)/0.7
=1.43
=1.4 [to the nearest tenth]
Answer:
No
Step-by-step explanation:
We can plug in the ordered pair (6,-1) into the equation. Remember that 6 is the x coordinate therefore we plug it in for x and that -1 is the y coordinate so we should plug it in for y.
6x+3y=6(6)+3(-1)=36-3=33
Since 33 is not equivalent to 15, (6, -1) is not a solution to the equation.
