Answer:

$\huge\boxed{-28}$

Step-by-step explanation:

We can substitute the given values of $a$ , $b$ , and $c$ to find the value of this expression.

$-4 | a + b - c|$

$-4 | 3 + (-2) - (-6)|$

We know that <em>two negatives make a positive. </em>This means that $-2 - (-6)$ will be the same this as $-2+6$

$-4 | 3 + -2 + 6|$

Adding a negative is the same as subtracting a positive.

$\4 | 3-2+6|\\\\3-2+6 = 7$

$-4 \cdot 7 = -28$

Hope this helped!

Y/3 - 4 = -1 solve for y

Marysya12 [62]

Answer:

y=9

Step-by-step explanation:

First we need to solve al addition and subtraction by performing the inverse operation. In this case, we need to add to reverse the subtraction

y/3 -4= -1

y/3= 3

Now we solve all multiplication and division again using the inverse operation, which in this case is multiplication, because the variable is being divided.

y/3=3

y=9

Thus we get that the value for y is 9.

Identify the triangle PQR as isosceles (two sides of equal length), equilateral (three sides of equal length), or a scalene

Ipatiy [6.2K]

Answer:

Isosceles

Step-by-step explanation:

In order to figure what type of triangle this is out, we need to start by plotting the given points. That will help us visualize the triangle better and see if our conclusions make sense. (See attached picture).

Once we got the triangle, the strategy to follow is to use the distance between two points formula to see what the measurement of each side of the triangle is. This will help us determine if 2, 3 or none of the sides of the tirangle are the same.

The distance formula is the following:

$distance=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}$
