Answer:

Any number less than -17

Step-by-step explanation:

Subtract 9 from -8. Any number less than the total is less than -8.

-8 - 9 = -17

-17 + 9 = -8

Ex:

-18 + 9 < -8

-19 + 9 < -8

-20 + 9 < -8

Which Postulate/Theorem below would prove that the triangles shown below are congruent?
velikii [3]

Answer:

Correct answer is <em>D. ASA</em>

<em />

Step-by-step explanation:

Let us first define <em>ASA congruence</em> rule:

2 triangles are called congruent according to ASA congruence rule if 2 angles of the triangle and the corresponding side between these two angles are <em>equal </em>to each other.

In the question figure, we can figure out following conclusions from Triangles \triangle SRT\text{ and }\triangle WXY respectively:

  1. \angle TRS = \angle YXW
  2. Side RS = Side WX
  3. \angle TSR = \angle YWX  

As per the definition of option d) ASA congruence, the triangles are congruent.

Help please !!!!!!!!!!!!!!

1) The triangles are similar, so correponding sides have the same ratio.
.. 3x/20 = (4x +2)/28
.. 3x/5 = (4x +2)/7 . . . . . . . multiply by 4
.. 7*3x = 5(4x +2) . . . . . . . multiply by 35 = 5*7
.. 21x = 20x +10 . . . . . . . . eliminate parentheses
.. x = 10 . . . . . . . . . . . . . . . subtract 20x


2) The triangles are similar, so corresponding measures have the same ratio.
.. x/42 = 10/15
.. x = 42*(10/15) = 28


3) The third angle of triangle ABC is 180° -20° -80° = 80°. Then two of the angles of ABC match those of JKL. The 3rd answer selection is appropriate.

What is the slope of the line that contains the points (-4,2) and (6,-3)?-
schepotkina [342]

Answer:

c

Step-by-step explanation:

the formula is \frac{y_{2}-y_{1} }{x_{2} -x_{1}}

When we plug that in we get \frac{-3-2}{6- (-4)} = \frac{-5}{10} = -\frac{1}{2}

Hope this helps!
