What is the slope that passes through (-9,-8) and (-15,-16)

guapka [62]

Answer:

Slope = $\frac{4}{3}$

Step-by-step explanation:

(-9, -8) & (-15 , -16)

Slope = $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$= \frac{-16-[-8]}{-15-[-9]}\\\\= \frac{-16+8}{-15+9}\\\\= \frac{-8}{-6}\\\\= \frac{4}{3}$

Which perfect square equation represents x^2+4x+1=0 by completing the square?

natali 33 [55]

First thing to do is to move the constant over to the other side of the equals sign. Then we will complete the square on the x terms. We will take half the linear term, square it, then add it to both sides. Our linear term is 4. Half of 4 is 2, and 2 squared is 4. $x^2+4x+4=-1+4$ . In the process of completing the square we have created a perfect square binomial on the left which is $(x+2)^2=3$ . A is our answer.

The figure below shows a triangle with vertices A and B on a circle and vertex C outside it. Side AC is tangent to the circle. S

JulsSmile [24]

Answer:

Step-by-step explanation:

First, one theorem states that (arc AB - arc AX) / 2 = angle ACB. We know that arc AB is 176, so we have

(176 - arc AX) /2 = ∠ACB

Next, the Inscribed Angle Theorem states that

arc AX/2 = ∠ABX

multiply both sides by 2

56 * 2 = arc AX = 112

Therefore, ∠ACB = (176-112)/2 = 64/2 = 32
