The sum of 14 and a number is 14+x

we know that this equals 17, so: 14+x=17.

Let's substract 14 from both sides:

x=17-14

x=3

so the number is 3.

<h3>Inequalities</h3>

Let the price of each pencil Marco can buy be "x"

If the cost of markers is $4, and the cost of each lead pencil is $3 with at most $15 spent, hence;

4 + 3x ≤ 15

Subtract 4 from both sides

3x ≤ 15

x ≤ 15/3

x ≤ 5

This shows that Marco can buy at most 5 pencils

An electric utility company determines the monthly bill for a residential customer by adding an energy charge of 7.32 cents per

Sedaia [141]

Answer:

$y(x) = 0.0732x + 17.32$

Step-by-step explanation:

The equation for the monthly charge has the following format

$y(x) = ax + b$

In which y(x) is the cost in function of the number of kilowatt-hours used(x), a is the price of each killowatt hour and b is the fixed(base) charge.

Base charge of $17.32 per month.

This means that $b = 17.32$

charge of 7.32 cents per kilowatt-hour

Our answer is in dollars. Each dollar is 100 cents. So 7.32 cents is $a = 0.0732$

Write an equation for the monthly charge y in terms of x, the number of kilowatt-hours used.

$y(x) = ax + b$

$y(x) = 0.0732x + 17.32$
