Line m is perpendicular to x − 5y = −1 and passes through (2, 9). What is the slope of line m?

Answer:

Slope of line M= -5

Step-by-step explanation:

Perpendicular lines have opposite reciprocals for slope.

For ex: 1/2x=y is perpendicular to -2x=y

For this one simplify the first equation:

x+1=5y

x/5+1/5=y

The slope of the original equation is 1/5.

So the slope of the perpendicular line would be -5.

The actual equation would be:

-5x+19=Y

Answer:

  BC = 5

Step-by-step explanation:

Of course, this geometry program can tell you the length of BC.

__

If you follow directions, you get a right triangle BCF that has leg lengths 3 and 4. The Pythagorean theorem then tells you the length of hypotenuse BC is ...

  BF = 4 -1 = 3

  FC = 4 -0 = 4

  BC² = BF² +FC²

  BC² = 3² +4² = 9 +16 = 25

  BC = √25

  BC = 5

138.72 - 45.23 - 18
These are the check costs that subtracted from her bank account
75.49 is what you get
A deposit is when you add money to your account, so, you add 75.85
75.49 + 75.85 = $151.34

Help pleaseeeeee!!!!!!!!!!!!!!!
diamong [38]

Answer:

2 meters

Step-by-step explanation:

We need to use trigonometry for this. The appropriate one would be tangent, which is (opposite side) divided by (adjacent side).

In this case, the opposite side of angle A is BC, which is 6 meters. The adjacent side of angle A is AB, which is the ground. Since we don't know its length, we call it x.

Now, we write:

tan(72) = 6/x

To solve, we just multiply both sides by tan(x) and x:

x = 6/[tan(72)] ≈ 1.95 meters ≈ 2 meters.

Thus, the answer is 2 meters.

Hope this helps!
