Answer:
3.6
Step-by-step explanation:
replace x with -3
f(-3)=0.6(3-(-3))
f(-3)=0.6(6)
f(-3)=3.6
X=-12 because you subtract the 9 since it is positive and bring it to the -3 and that gets you -12 and subtract the x from 2x because it is positive and you get x=-12
Answer:
Hence, the system of equation does not have solution.
Step-by-step explanation:
You have the following 2x2 system:
You can obtain the solution to the system by using substitution method.
You solve the first equation for x:
(3)
Next, you replace (3) in the equation (2), and you solve for y:
The last result is the trivial solution. This means that the equation (2) is a multiple scale of the first equation. In fact, if you multiply equation (1) by -4, you obtain the equation (2).
Hence, the system of equations does not have solution.
