Please help me solve this

a) reflection across the x-axis, shift 8 units left

b) vertical stretch of 2, reflection across the y-axis, shift up 1

Step-by-step explanation:

The negative sign outside the square root represents a reflection across the x-axis, and the +8 inside represents a shift 8 to the left

The 2 outside the square root represents a vertical stretch of 2, and the negative sign inside the square root represents a reflection across the y-axis. The +1 at the end represents a shift up 1

step-by-step explanation:

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
