A supermarket offers a delivery service. If a customer pays $9 per month, each delivery costs just $2. Write an equation that sh

Rzqust [24]

The linear function that models the total cost for x deliveries is:

$y(x) = 2x + 9$

-------------------

A linear function has the following format:

$y = mx + b$

In which

m is the slope, that is, the rate of change.
b is the y-intercept, that is, the value of y when x = 0.

In this problem:

Fixed cost of $9 per month, $b = 9$ .
Cost of $2 for each delivery, thus $m = 2$ .

The function for the <u>total cost for x deliveries is:</u>

$y(x) = 2x + 9$

In triangle XYZ, angle Y = 45º and angle Z = 60º. If XZ = 4, then what is XY?

Katena32 [7]

Answer:

$XY = 4.9$

Step-by-step explanation:

Given

$XZ= 4$

$\angle Y = 45$

$\angle Z = 60$

Required

Determine the measure of side XY

To do this, we make use of sine law. This is as follows:

$\frac{a}{\sin\ A} = \frac{b}{\sin\ B} = \frac{c}{\sin\ C}$

In this case:

$\frac{4}{\sin(45)} = \frac{XY}{\sin(60)}$

Cross Multiply

$XY * \sin(45) = 4 * \sin(60)$

$XY * 0.7071 = 4 * 0.8660$

Make XY the subject

$XY = \frac{4 * 0.8660}{0.7071}$

$XY = \frac{3.4640}{0.7071}$

$XY = 4.89888276057$

$XY = 4.9$ -- <em>approximated</em>
