Answer:

Angle ACE is approximately equal to Angle ECA

Step-by-step explanation:

we know that

In the figure

The vertex C is a common vertex of triangle ACE and triangle ACD

therefore

m<ACE=m<ACD

m<ACE=m<ECA

The first one is correct because the angle on the opposite side is the same, and the second one is correct too because it's the same points. So you can pick either or.

REVIEW: Find the slope for the following situations. a. Given the equation y = 5x + 1 b. Given the equation 2x + y = 6 c. Given

DanielleElmas [232]

Answer:

Part 1) The slope is $m=5$

Part 2) The slope is $m=-2$

Part 3) The slope is $m=2$

Step-by-step explanation:

Part 1) we know that

The equation of the line into slope intercept form is equal to

$y=mx+b$

where

m is the slope

b is the y-coordinate of the y-intercept

In this problem we have

$y=5x+1$

the slope is $m=5$

Part 2) we know that

The equation of the line in standard form is equal to

$Ax+By=C$

where

the slope is equal to $m=-\frac{A}{B}$

in this problem we have

$2x+y=6$

$A=2,B=1,C=6$

substitute

$m=-\frac{2}{1}$

$m=-2$

Part 3) we know that

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

we have

$A(2,3)\ B(5,9)$

Substitute the values

$m=\frac{9-3}{5-2}$

$m=\frac{6}{3}$

$m=2$
