Step-by-step explanation:

1. a) vertical stretch by a factor of 5 and

  e) reflection over x-axis

2. c) reflection over the y-axis

   e) horizontal shift to the right 4 units

3. c) horizontal shift

Answer:

$2.70

Step-by-step explanation:

Cost price = $6

Mark up percentage = 45%

Mark up amount = 45% × $6

                           = 0.45 × $6

                           = $2.70

Selling price = Mark up + cost price

                     = $2.70 + $6

                     = $8.70

Jermaine sells the shirts for $8.70 and makes a profit of $2.70.

Answer:

$2.70

Step-by-step explanation:

6*45% =2.70

The two numbers multiply to 64 and add up to negative 16 are -8, -8.

What is Algebraic expression ?

Algebraic expressions are numbers expressed using letters or alphabets without specifying their values. Algebra taught us how to express unknown values using letters such as x, y, and z. There can also be a single value that is placed before and multiplied by a variable in an algebraic expression in addition to these letters, which are called variables.

Let us assume first number be = x

and, let the second number be = y

then,

multiplication of two number will be :

xy = 64...(1)

addition of two numbers will be -16 that is :

x + y = -16..(2)

we have :

(x+y)² - (x-y)² = 4xy

(x-y)² = (x+y)² - 4xy

(x-y)² = (-16)² - 4 x 64

(x-y)² = 256 - 256

(x-y)² = 0

(x-y)  = 0

x = y

Now, from equation (2) we have ":

x + y = -16

x + x = -16

2x = -16

x = y= -8

Therefore, the two numbers multiply to 64 and add up to negative 16 are -8, -8.
