What theorem or postulate can be used to justify that the two triangles are congruent? Write a congruence statement.

Alinara [238K]

ASA is short for angle side angle, which you can see from angle B and angle D being congruent (all right angles are congruent), the congruent marks on line BE and line ED, and the vertical angles AEB and DEC.

D is not the answer because B and D are not in the same 'place' when naming. Silly as it is, it counts.

Hope this helps!

The number line below represents the solution to which inequality?

Vladimir [108]

Answer:

Step-by-step explanation:

We are given with a

FILLED CIRCLE : If circle is filled that means that that point is also included in the number line solution.

here we are given that the arrow is pointing left from -2 and the circle is filled

hence -2 is included and as the arrow is pointing towards left towards negative , the includes all the point less or equal to -2

The solution of the in equation would be

x ≤ -2

Unfortunately none of the option gives the above value of x.

Complete the expression that represents the table<br><br> Y=___x

bezimeni [28]

Answer:

The equation that represents the table is:

$y=\frac{9}{2}x$

Step-by-step explanation:

Taking two points from the table

(2, 9)

(4, 18)

$\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$\left(x_1,\:y_1\right)=\left(2,\:9\right),\:\left(x_2,\:y_2\right)=\left(4,\:18\right)$

$m=\frac{18-9}{4-2}$

$m=\frac{9}{2}$

As the slope-intercept form is

$\:y=mx+b$

Plugging (2, 9) to find the y-intercept 'b'

$9=\frac{9}{2}\left(2\right)+b$

$\mathrm{Switch\:sides}$

$\frac{9}{2}\left(2\right)+b=9$

$\mathrm{Remove\:parentheses}:\quad \left(a\right)=a$

$\frac{9}{2}\cdot \:2+b=9$

$9+b=9$

$b=0$

so the equation becomes

$\:y=mx+b$

$m=\frac{9}{2}$

$b=0$

$y=\frac{9}{2}\left(x\right)+0$

$y=\frac{9}{2}x$

Therefore, the equation that represents the table is:

$y=\frac{9}{2}x$

The graph of the equation is also attached below.
