The extensions of the legs AB and CD of a trapezoid ABCD intersect at point E. Find the lengths of the altitude of △AED drawn to

Gnom [1K]

let's call G the intersection point of EF & BC.

according to the thales' theorem:

$\frac{eg}{ef} = \frac{bc}{ad}$

and EF= EG+GF=EG+3

$\frac{eg}{eg + 3} = \frac{7}{21}$

$21eg = 7eg + 21$

$14eg = 21$

$eg = \frac{21}{14} = \frac{3}{2} = 1.5$

length of the altitude of △AED=EF

EF=EG+GF=1.5+3=4.5

I'm trying to figure out how much money I'm left with

Salsk061 [2.6K]

the answer is 60.35, because the 70$ answer is how much you get after work, then the 62$ one is after you pay the 12$ for dinner but then the 60.35 is how much you’re left with after you leave the tip

If x-9 is a factor of x-5x-36 what is the other factor

dimaraw [331]

The other factor would be (x + 4). We can find this by using synthetic division. To do this, we must first find the divisor, which would be 9, if we let x - 9 equal to zero and solve for x. Then, for the dividend, we can use the coefficients and constant term values.
<u>9</u>| 1 -5 -36
<u> 9 36</u>
1 4 0
Therefore, the other expression (x + 9) would be (x + 4). Hope this helped!

Stella graphs the equation y=1/3x – 2

faltersainse [42]

we have

$y=\frac{1}{3}x-2$

<u>Statements</u>

<u>case A)</u> The graph is a straight line.

The statement is True

Because, this is a linear equation (see the attached figure)

<u>case B)</u> The line passes through the origin.

The statement is False

Because the point $(0,0)$ is not a solution of the equation

Verify

Substitute the value of x and y in the equation

$0=\frac{1}{3}*0-2$

$0=-2$ ------> is not true

the point $(0,0)$ is not a solution

therefore

The line does not pass through the origin

<u>case C)</u> The line passes through the point $(0,-2)$

The statement is True

Because the point $(0,-2)$ is a solution of the equation

Verify

Substitute the value of x and y in the equation

$-2=\frac{1}{3}*0-2$

$-2=-2$ ------> is true

the point $(0,-2)$ is a solution

therefore

The line passes through the point $(0,-2)$

<u>case D) </u>The slope of the line is $3$

The statement is False

Because, the slope of the line is $m=\frac{1}{3}$

<u>case E)</u> The y-intercept of the line is $2$

The statement is False

we know that

The y-intercept is the value of y when the value of x is equal to zero

so

For $x=0$

find the value of y

$y=\frac{1}{3}*0-2=-2$

the y-intercept is equal to $-2$
