The formula for finding the distance between two points is this:
$\sqrt{} (x_{2} -x_{1})^{2} + (y_{2} -y_{1} )^{2}$

The person subtracted the variables incorrectly and subtracted x1 from x2 and y1 from y2 instead of the other way around.

To correctly solve it, do this: $\sqrt{((-7-(-1))^2+(-6-2)^2} = \sqrt{(-6)^{2} + (-8)^{2} } = \sqrt{36+64} = \sqrt{100} = 10$

Hope this helped!

The store is selling lemons at $0.58 each. Each lemon yields about 2 tablespoons of juice. How much will it cost to buy enough l

avanturin [10]

Answer:

$4.64

Step-by-step explanation:

1 cup = 16 tablespoons

$\frac{1}{2}$ cup = 8 tablespoons

Each lemon yields about 2 tablespoons of juice. You need 8 tablespoons for one lemon pie, so you need $8\div 2=4$ lemons for one pie and $4\times 2=8$ lemons for two pies.
