Describe the piecewise function below by evaluating the function for given values of the domain
tekilochka [14]
We have a piecewise function.
 Therefore, to find the function, we must evaluate each domain separately.
 We have then:

 For x  \leq  -2:
 The function for this domain is:
 y = -3


 
For -2 \ \textless \  x  \leq  2:
 
The function for this domain is:
 y = mx + b

 Where,
 b = -3

 m = (y2 - y1) / (x2 - x1)

 m = (1 - (-7)) / (2 - (-2))
 m = (1 + 7) / (2 + 2)

 m = 8/4

 m = 2
 Substituting:
 y = 2x - 3


 
For x\ \textgreater \  2:
 
The function for this domain is:
 y = 5

Erica’s family is moving away from California. They decided to have a moving sale and sell each item for 70% off the price they
Burka [1]

Find the sale price by multiplying the original price by 70% then add the two prices together to get the total.

799 x 0.70 = 559.30

549 x 0.70 = 384.30

Total: 559.30 + 384.30 = $943.60

KatRina [158]

Answer:

a) 1.8 cm^2

b) 3.6 feet^2

Step-by-step explanation:

Conversion and calculation of areas

The area of a rectangle is A=wh, where w is the width and h is the height. There are 3 feet in one yard

a)

We are told Kalie put 6 stickers, each one of 1/2 centimeters (0.5 cm) wide by 3/5 (0.6 cm) centimeter long. The area of one sticker is

A=(0.5)(0.6)=0.3 cm^2

Assuming there is no overlapping, the 6 stickers have a total area

6*0.3 cm^2=1.8 cm^2

b)

Each of Elana's wrapping papers measures 2/5 yards long and 1/4 yard wide. Converting them to feet we have

long=2/5*3=1.2 feet

wide=1/4*3=0.75 feet

Area of each paper=1.2 feet*0.75 feet=0.9 feet^2

Area of the entire board, assuming no overlapping and no space left uncovered=4*0.9 feet^2

Area of board=3.6 feet^2
