Answer:

-30

Step-by-step explanation:

I'm assuming the equation is $4m-n$ . If it is not please tell me.

If we know the values of m and n, we can just substitute inside the expression.

$4(-7) - 2\\\\-28 - 2\\\\-30$

Hope this helped!

HELP PLZ!!!!!!! Is the following graph a function?

Stels [109]

This graph does not represent a function because the x-intercepts repeat themselves several times. In order for a graph or group of coordinates to be a function, there must be only one of a particular x-coordinate.

Pls help. What is the appropriate congruent for these triangles

tekilochka [14]

Answer:

ASA

Step-by-step explanation:

In given triangle

Line BC = Line QR

Angle ABC = Angle PQR

Angle ACB = Angle PRQ

Computation:

Angle ABC = Angle PQR (Angle)

Line BC = Line QR (Side)

Angle ACB = Angle PRQ (Angle)

So,

ΔABC ≅ ΔPQR

By Angle Side Angle property

Answer:

$f(g(x))=\dfrac{|x|+1-||x|-1|}{2}$

Step-by-step explanation:

The most straightforward way is direct substitution of g(x) for x in f(x):

$f(g(x))=\dfrac{|x|+1-||x|-1|}{2}$

I need help asap!!!!!

Answer: 130

In order to solve for <4, you need to know that supplementary angles add up to 180°.
<3 = 50
180 - 50
130

**For future questions**
1. The sum of the interior angles of a triangle is 180°
2. Alternate interior angles are congruent
3. The exterior angle of a triangle is the sum of the nonadjacent interior angles
