A. x=the cost of one lunch. 60.25=5x+3(x-5.25)
b. 60.25=5x+3x-15.75 60.25+15.75=8x-15.75+15.75
76=8x 76/8=8x/8 9.50=x
A lunch is $9.50. If you are not sure, check my answers. Hope this helped.
The value of (f - g)(x) is -x - 14
<h3>How to evaluate the function?</h3>
The given parameters are:
f(x) = 4x - 8
g(x) = 5x + 6
To calculate (f - g)(x), we make use of
(f - g)(x) = f(x) - g(x)
So, we have:
(f - g)(x) = 4x - 8 - 5x - 6
Evaluate the like terms
(f - g)(x) = -x - 14
Hence, the value of (f - g)(x) is -x - 14
