Answer:

Step-by-step explanation:

Increase

Increase = \dfrac{4}{5}-\dfrac{2}{5}=\dfrac{2}{5}

Increase percentage = 2/5 out of 2/5 * 100

                                    =\dfrac{2}{5}*\dfrac{5}{2}*100

                                     = 100 %

Oliga [24]

Answer:

slope is undefined

Step-by-step explanation:

Calculate the slope m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (- 2, 9 ) and (x₂, y₂ ) = (- 2, - 5 )

m = \frac{-5-9}{-2-(-2)} = \frac{-14}{-2+2} = \frac{-14}{0}

Since division by zero is undefined then the slope is undefined

Therefore, the fraction of smoothies sold were either banana or strawberry is  \frac{11}{12}.
