Answer:
Step-by-step explanation:
Given equations are
15x + 15y + 10z = 106
5x + 15y + 25z = 135
15x + 10y - 5z = 42
The augmented matrix by using above equations can be written as
Hence, we can write from augmented matrix,
By radical do you mean the square root symbol?
Answer:
It makes sense at the beginning, but I'm sure that there's a second part??
Step-by-step explanation:
Sorry love
Hello!
For this you can plug in the x values in the choices and see if you get the y value
y =
-4^3 is -64
when you subtract a negative you are just adding
-64 + 4 = 60
Then you do the second one
-3^3 is -27
-27 + 3 is -24
Then the third one
-2^3 is -8
-8 + 2 is -6
Then the last one
-1^3 is -1
-1 + 1 = 0
Since we did not get -2 the answer is D
Hope this Helps!
