Answer:

3x^2-x+3

Step-by-step explanation:

\left(x^2+3x+2\right)+\left(2x^2-4x+1\right)

<u>⇒ Remove parentheses:-</u>

<u />x^2+3x+2+2x^2-4x+1

<u>⇒ Combine like terms:-</u>

<u />x^2+2x^2+3x-4x+2+1

<u>⇒ Add similar elements:-</u>

<u />3x^2-x+2+1

3x^2-x+3

What is the slope of a line that passes through (-4,-13) and (19,11)
inysia [295]
The slope of the line is the gradient, which you can find through rise over run

m (gradient) = (y1 - y2) / (x1 - x2)

where (x1, y1) is the coordinate of the first point, and (x2, x2) is the coordinate of the second point

in your question: 
x1 = -4
x2 = 19
y1 = -13
y2 = 11

m = (-13 -11) / (-4 -19) = -24 / -23 = 24/23 or 1.04 (2d.p.)

hope that helps :)

A quadrilateral WXYZ contains wxy where measure of wxy=92 degrees. Once rotated 270° about the origin and translated 2 units up,
Marianna [84]

Answer:

C. 92 degrees

Step-by-step explanation:

Given that the \angle{wxy}=92° which is one of the angles of the quadrilateral WXYZ

The quadrilateral is first rotated by 270° about the origin and then translated 2 units up, the new position of the quadrilateral is W'X'Y'Z'.

The shape of the quadrilateral is remained unchanged due to rotation and translation, so all the angles of the final quadrilateral W'X'Y'Z' is the same as the angles of the given quadrilateral WXYZ.

So,\angle{w'x'y'}= \angle{wxy}

By using the given value,

\angle{w'x'y'}= 92°

Hence, option (C) is correct.
