answer : x = 1
The graph of two functions are attached below
First function is f(x) = -2x+3
Second function g(x)=
We graph both the functions and find out the point where both graphs intersects
From the attached graph , we can see that both graph intersects at x= 1.08
So the solution for f(x)= g(x) is x=1

Answer:
For this case we want to check if the true mean for the depth of groves cut into aluminium by a machine is equal to 1.7 (null hypothesis) and the alternative hypothesis would be the complement different from 1.7. And the best system of hypothesis are:
Null hypothesis:
Alternative hypothesis
Alternative hypothesis [tex]\mu \neq 1.7[/tx]
And the best system of hypothesis are:
3. This two-sided test:
H0: μ = 1.7 mm
H1: μ ≠ 1.7 mm
