Answer:

Okay, there are many ways to find if a triangle is congruent.

Let's start with some different terminology.

For the sake of simplicity let us say that S stands for when a side is congruent for both triangles and A stands for when an angle (<) is congruent between both the triangles as well.

So, you need to memorize some rules. If you find that 2 triangles are congruent in the sense of; SSS, SAS, AAS, SAA, and ASA. One thing to remember is that Angle Side Side isn't congruent and is called <em>Donkey Theorem</em>. This theorem only works for right triangles.

One way to know if your triangle isn't congruent is if you can find a part of the triangle that is different.

I know that wasn't the best explanation but I hope it helped anyhow. :)

Determine the missing y value if the slope of a line is 4/3 and the line passes through the points (5,x) and (2,-3)
Simora [160]

Answer:

x = -7

Step-by-step explanation:

Given parameters:

Slope of the line = \frac{4}{3}

 Coordinates =  (5,x) and (2,-3)

Unknown:

X= ?

Solution:

  To find slope, use the expression below;

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

y₂ = -3  y₁ = x

x₂ = 2   x₁ = 5

   \frac{4}{3}  = \frac{-3 - x}{2 - 5}

           3(-3-x) = 4(-3)

            -9 -3x = 12

                -3x = 21

                  x = -7

What is the answer to this function p(15)=-2(x-9)^2+100
vovangra [49]

Answer:

28

Step-by-step explanation:

p(x)=-2(x-9)^2+100

Let x= 15

p(15)=-2(15-9)^2+100

Parentheses first

      = -2 ( 6) ^2 + 100

Then exponents

     = -2 * 36 + 100

Then multiply

    = -72 + 100

Then add

   =28

Are 2(x - 3) + 1 and 2x + 6 equivalent expressions​
KATRIN_1 [288]

Answer:

No.

Step-by-step explanation:

2(x-3) + 1  = 2x - 6 + 1 = 2x - 5

2x + 6   ≠   2x -5, so no, they aren't equivalent.
