Answer:

x=20

Step-by-step explanation:

Because all angles of a triangle add up to 180, by adding all the values that your given and setting it equal to 180, you get the value of x.

3x+2x+20+4x-20=180

9x=180

x=20

Which phrase best describes the translation from the graph y = (x + 2)2 to the graph of y = x2 + 3?
Mashutka [201]

1. Consider the transformation that maps the graph of the function y=(x+2)^2 into the graph of the function y=x^2. This transmormation has a rule:

(x,y)→(x+2,y)

that is translation 2 units to the right.

2. Consider the transformation that maps the graph of the function y=x^2 into the graph of the function y=x^2+3. This transformation has a rule:

(x,y)→(x,y+3)

that is translation 3 units up.

Answer: correct choice is C.

Add the following polynomials, then place the answer in the proper location on the grid.
aivan3 [116]

Answer:

x^3 - 6x + 2

Step-by-step explanation:

The given polynomials can be added together by adding like terms together as shown below:

=> Add together, the coefficient of all terms that have the power of 3.

(2x^3) + (x^3) + (-3x^3)

2x^3 + x^3 - 3x^3

3x^3 - 3x^3

x^3

=> (-4x^2) + (6x^2) + (2x^2)

-4x^2 + 8x^2

4x^2

=> (6x) + (-8x) + (-4x)

6x - 8x - 4x

-6x

=> (-3) + (12) +(-7)

-3 + 12 - 7

2

The answer = x^3 - 6x + 2
