On a separate piece of graph paper, graph y = -|x + 1|; then click on the graph until the correct one appears

See picture for graph.

Step-by-step explanation:

The graph of an absolute value is a V shape function. The negative in front turns the V upside down. The (x+1) determines the x-coordinate of the vertex. The vertex will be (-1,0). See picture for the graph.

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
