Answer:

(a) f(2) = 81

(b) g(2) = 83

(c) Test average for maths class after test 2 is greater

Step-by-step explanation:

Given

f(x) = 0.5x + 80

x \to g(x)

1 \to 81

2 \to 83

3 \to 85

Solving (a): f(2)

We have:

f(x) = 0.5x + 80

f(2) = 0.5*2+80

f(2) = 1 + 80

f(2) = 81

Solving (b): g(2)

From the table:

g(x) = 83 when x = 2

So:

g(2) = 83

Solving (c): Which is greater f(2) or g(2)

In (a) and (b),

f(2) = 81

g(2) = 83

Hence, test average for maths class is greater

An equation is formed of two equal expressions. The number of people that can sit at a table is 6.

<h3>What is an equation?</h3>

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Let the number of people that can be seated at a table be represented by x, while the number of people that can be seated in a booth is y.

The equation for the two floor plans can be written as,

24x + 11y = 254

12x + 17y = 242

Solving the above equations, by plotting the two of the given equations. Therefore, the number of people that can sit at a table is 6.
