Solve the system of equations.
4x + 3y + 5z = 6
6x + 8y + 6z = 4
4x + 2y + 6z = 8
a (x = 1, y = - 1,z = 1)
b. (x = 3, y=-3, z = 3)
c. (x = 0, y = 0,2 = 2)
d. (x = 2, y = -2,2=0)

Can someone me with this problem . show your work .

F(n + 1) = f(n) – 8. if f(1) = 100, what is f(6)?

Create a question with this scenario you could ask that could be answered only by graphing or using logarithm. david estimated he had about 20 fish in his pond. a year later, there were about 1.5 times as many fish. the year after that, the number of fish increased by a factor of 1.5 again. the number of fish is modeled by f(x)=20(1.5)^x.
