The independent variable in these equations based on how they are written is x, since y is a function of x here so y depends on the value of x, while x can be changed freely.
So, for each of these questions, plug in the given value of the independent variable for x.
Independent variable equal to 10: 0.1*10 + 5 = 6
Independent variable equal to 50: 0.1*50 + 5 = 10
Independent variable equal to 120: 0.1*120 + 5 = 17
Ok to figure out if one is an inverse function, you plug in y for x and substitute f(x) with x and solve for y.
We only have to do this for 1 of the functions so we will take f(x)
x = 5y +1/y
I’m not sure you can solve for y here therefore g(x) is not an inverse function of f(x)
Answer:
x = -3
y = 9
Step-by-step explanation:
you can add the equations after multiplying the first one by 8
8x - 8y = -96 added to -8x - 4y = -96
'x' eliminated; -12y = -108; y = 9
Solve for 'x':
x - 9 = -12
x = -12 + 9
x = -3
They each get 2/3 a sandwich
Answer:
3x-2
Step-by-step explanation:
can be factored using the perfect square rule into 
and
can be factored by using the difference of squares formula into 
Both can be factored by (3x-2) so it is a common factor.
