Find the distance between the following points using the Pythagorean theorem: (-5, 4) and (8, -3)
3241004551 [841]

First, draw a diagram to visualize the situation:

As we can see, the difference between the x-coordinates of the points is the length of one leg of a right triangle, and the difference between the y-coordinates is the length of the other leg.

Then, for the given points (-5,4) and (8,-3), the distance given by the Pythagorean Theorem is:

\begin{gathered} d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\  \\ =\sqrt{(8--5)^2+(-3-4)^2} \\  \\ =\sqrt{(13)^2+(-7)^2} \\  \\ =\sqrt{169+49} \\  \\ =\sqrt{218} \\  \\ \approx14.7648... \end{gathered}

Therefore, the distance between the points (-5,4) and (8,-3) is: √218.

1/5y + 1/8 =3/20 solve for y
Eddi Din [679]

Answer:

y=\frac{1}{8}

Step-by-step explanation:x_{3}

\frac{1}{5}y+\frac{1}{8}=\frac{3}{20}

multiply both sides

8y+5=6

move the constant to the right

8y=6-5

calculate

8y=1

divide both sides

y=\frac{1}{8} or y=0.125
