7x-5y=-6

1 answer:

8 0

The perpendicular line would have a slope of -5/7.

Perpendicular lines have opposite and reciprocal slopes. So first we have to find the slope of the original line. We can do this by solving the equation for y.

7x - 5y = -6

-5y = -7x - 6

y = 7/5x + 6/5

To do the opposite, take the original slope (7/5) and change the sign (-7/5).

To do the reciprocal, take the slope we changed (-7/5) and flip it as a fraction (-5/7).

This gives us a new slope of -5/7.

Distance between (-1,-3) and (-9,2)

Lisa [10]

The formula of a distance between two points:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

We have the points (-1, -3) and (-9, 2). Substitute:

$d=\sqrt{(-9-(-1))^2+(2-(-3))^2}=\sqrt{(-8)^2+5^2}=\sqrt{64+25}=\sqrt{89}$

<h3>Answer: d = √89</h3>

The perimeter of a rectangle is 76 meters. Find the length and width if the length is an even integer and the width is 3 times t

AlekseyPX

Answer:

Length = 8 m

Width = 30 m

Step-by-step explanation:

Let length = x.

Then width = 3(x + 2).

P = 2(L + W)

76 = 2[x + 3(x + 2)]

76 = 2[x + 3x + 6]

76 = 2[4x + 6]

8x + 12 = 76

8x = 64

x = 8

3(x + 2) = 3(10) = 30

Answer:

Length = 8 m

Width = 30 m
