Answer:

Step-by-step explanation:

(f - g)(x) = f(x) - g(x)

We have f(x) = 27x + 3 and g(x) = x - 7. Substitute:

(f - g)(x) = (27x + 3) - (x - 7)

(f - g)(x) = 27x + 3 - x - (-7)

(f - g)(x) = 27x + 3 - x + 7 combine like terms

(f - g)(x) = (27x - x) + (3 + 7)

(f - g)(x) = 26x + 10

The equation of a straight line is an equation that comes in the form of an algebraic equation. It is also referred to as Slope - Intercept form. It can be represented using the equation below:

Equation : y = mx + c

where:

m = Gradient

c = Slope of the line

The equation that shows how the price of a personal pizza y, depends on the number of toppings x is y = 7 + x

This question can be solved and represented using the equation of a straight line.

Let's represent

y = price of a personal pizza

x = number of toppings

The price for a plain cheese pizza = $7

The price for each of the toppings = $1

Therefore, the equation that shows how the price of a personal pizza y, depends on the number of toppings x is written as:

y = $7 + $1 * x

y = 7 + x
