Answer:

y = - 3x + 19

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 3, thus

y = - 3x + c ← is the partial equation

To find c substitute (6, 1) into the partial equation

1 = - 18 + c ⇒ c = 1 + 18 = 19

y = - 3x + 19 ← equation of line

Brendan earns 25% more than his regular hourly rate d when he works on holidays. Write an expression to represent the hourly rat

Tanya [424]

Answer:

The expression that represents hourly rate Brendan earns working on a holiday is $1.25d$ .

Step-by-step explanation:

Given:

Regular hourly rate = d

Percent extra Money earned on holidays = 25% more

We need to find expression represent the hourly rate Brendan earns working on a holiday.

Solution:

Extra money earned on holidays can be calculated by Percent extra Money earned on holidays multiplied by Regular hourly rate.

framing in equation form we get;

Extra money earned on holidays = $\frac{25}{100}d=0.25d$

Now we will find hourly rate Brendan earns working on a holiday.

hourly rate Brendan earns working on a holiday can be calculated by sum of Regular hourly rate plus Extra money earned on holidays.

framing in equation form we get;

hourly rate Brendan earns working on a holiday = $d+0.25d=d(1+0.25) =1.25d$

Hence The expression that represents hourly rate Brendan earns working on a holiday is $1.25d$ .
