Answer:

SSS

Step-by-step explanation:

Well, the picture says asks why the triangles are congruent but your question asks why they aren't congruent, so I will just assume that you made a typo, and you really meant: "Which rule explains why these triangles are congruent?"

Well, the triangles have two congruent sides, and they have a common shared side that are both congruent (due to reflexive property), so the triangle theorem SSS (Side-Side-Side) proves that the triangles are both congruent.

Write an equation for the line in point slope form through the points (2, −6) and (−1, −8).

igomit [66]

Let point A be $(2, -6)$ and point B $(-1, -8)$

$m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-8 - (-6)}{-1 - 2} = \frac{-8 + 6}{-1 -2} = \frac{-2}{-3} = \frac{2}{3}$

Use the point-slope formula and whichever point you want as , in this case I'll use

$y - y_1 = m(x - x_1)\\y - (-6) = \frac{2}{3}(x - 2)\\y + 6 = \frac{2}{3}x - \frac{4}{3}\\y = \frac{2}{3}x - \frac{4}{3} - 6\\y = \frac{2}{3}x - \frac{14}{3}$

If there are five different breads, eight meats, five cheeses, and five special sauces, how many different sandwiches are possib

Papessa [141]

Answer:

There are 1000 different sandwiches possible.

Step-by-step explanation:

The number of breads available is, 5.

The number of meats available is, 8.

The number of cheese available is, 5.

The number of special sauces available is, 5.

Assuming that a person is allowed 1 selection of each category.

The possible number of sandwiches that can be made is:

$=5\times8\times5\times5\\=1000$

Thus, there are 1000 different sandwiches possible.
