1. The value of (cd)(x) is equal to the product of c(x) and d(x) which is equal to,
5(x + 3) / (x - 2)
The function can take all real numbers except 2 because that would make the denominator 0.
2. To answer, substitute first 5 to the given functions,
f(x) = 7 + 4x = 7 + 4(5) = 27
g(x) = 1/2x = 1 / (2)(5) = 1/10
Dividing 27 by 1/10 is 270.
In the slope intercept form equation of a line (y=ax+b) a represents the slope, and b represents the intercept, which is -5. Thus, we know y=ax-5. The slope can be found by creating a fraction with the change in y value on top, and the change of x value on the bottom. If we have two points (4, 1) and (0, -5) we can put this into a fraction -

, which simplifies down to -6/-4, or 3/2. Thus the answer is f(x)=

Answer:
The answer is £4.16
Step-by-step explanation:
26 x 16 = 416 = £4.16
2x - 3 > 11 - 5x |add 3 to both sides
2x > 14 - 5x |add 5x to both sides
7x > 14 |divide both sides by 7
x > 2
x = 4
