Answer:

no

Step-by-step explanation:

easy way to find out...just do some subbing...but remember, for it to be a solution to this system, it has to satisfy both equations.

(2,3)...x = 2 and y = 3

-x + 4y = -9

-2 + 4(3) = -9

-2 + 12 = -9

10 = -9 (nope).....no need to check the other one because it does not satisfy this one.

It is NOT a solution

Evaluate (distributive property)
OLEGan [10]

Answer:

Step-by-step explanation:

If A, B and C are integers, according to distributive property;

A(B+C) = AB+AB

A is distributed over B and C

Given

9×6 = 5 sixes +4 sixes

5 sixes = 5(6) =30

4 sixes = 4(6) =24

9×6 = 5(6)+4(6)

9×6 = 30+24

9×6 = 54

Hence ? =5,?? =24 ??? = 54
