Answer:

I dont know the answer but I found out how you figure out if lines are supplementary

Step-by-step explanation:

1) let the measure of one of the supplementary angles be a

2) measure of the other angle is 2 times a

What is an equation of a circle whose center is at (2,-4) and is
Evgesh-ka [11]

The equation of the circle with center at (2,-4) and tangent to the line x = -2 is given by:

(2) (x - 2)² + (y + 4)² = 16

<h3>What is the equation of a circle?</h3>

The equation of a circle of center (x_0, y_0) and radius r is given by:

(x - x_0)^2 + (y - y_0)^2 = r^2

The circle has center at (2,-4), hence x_0 = 2, y_0 = -4.

The center is tangent to the line x = -2, hence it has a point at x = -2, since |-2 - 2| = 4, r = 4 -> r² = 16.

Hence the equation of the circle is given by:

(2) (x - 2)² + (y + 4)² = 16

Raj weighs a book and rounds the weights to the nearest tenth. Does this weight round to 1.5 pounds?
mel-nik [20]

Step 1: Locate and underline the tenth place (4) and look to the right (8)

1.48

Step 2: In this case, the digit to the right 8 is 5 or above. So, we add 1 to the tenth place 4. The digit at the right 8 becomes 0, thus we get 1.5 as the answer.

In short: 1.48 rounded to the nearest tenth is 1.5.

Hope that helped
