Answer:
x=2, y=-1, z=3
Step-by-step explanation:
The system shown in the attached picture can be solved using any method you wish
I think that the best way to go is by using the subtraction method,
First multiply the equation x+y+z=4 by 2, then sum it to the second equation.
This gives another equation: 4x+z=11.
If we subtract the first eq. with the third, we have another eq. -5x+z=-7.
Lest sum the 2 new founded equations, to obtain the following result: -9x=-18
thus, we obtain x=2
Next lets go backwards in the prior eq -5x+z=-7, with x=2, we obtain that z=3
Now in the first equation (x+y+z=4) we can substitute x=2, z=3 to obtain y value.
Answer:
Step-by-step explanation:
Hope that this is helpful .
Have a great day.
For this we need to take value of f(x) when x = -3 and value of f(x) when x = 2, sum them up and divide by distance between x = -3 and x = 2
f(-3) = -36
f(2) = 4
average rate of change is:
Avg = (36 + 4)/(3+2) = 8
Note that we have to use +36 and not -36 because we need distance from -36 and 4 and that is 36 + 4 = 40... same goes for -3
1/6 chances, saying if the dice has 6 sides.
