Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

f(x) = x/4 - 3

g(x) = 4x² + 2x - 4

(f + g)(x) is f(x) + g(x)

<u>Step 2: Find</u>

  1. Substitute in functions:                                                                                     (f + g)(x) = x/4 - 3 + 4x² + 2x - 4
  2. Combine like terms:                                                                                         (f + g)(x) = 4x² + 9x/4 - 7

The endpoints of two segments are given. Find each segment length to the nearest tenth. AB¯¯¯¯¯¯¯¯: A(0, 2), B(−3, 8) and CD¯¯¯¯
sleet_krkn [62]

Step-by-step explanation:

Pythagoras : the lengths are the hypotenuses of the right-angled triangles created by the differences of the x and the y coordinates.

so,

AB² = (0 - -3)² + (2 - 8)² = 3² + (-6)² = 9 + 36 = 45

AB = sqrt(45) ≈ 6.7

CD² = (-2 - 0)² + (2 - -4)² = (-2)² + 6² = 4 + 36 = 40

CD = sqrt(40) ≈ 6.3

I checked my answer on a graph and the line turned out to be horizontal. When the line is horizontal it is called a zero slope line. There is no slope.

Jan says that a rhombus is a parallelogram and that every parallelogram is also a rhombus. Is Jan correct?
marysya [2.9K]

Answer:

No

Step-by-step explanation:

A parallelogram has opposite sides parallel and equal in length. Also, opposite angles are equal. Squares, rectangles, and rhombuses are all parallelograms. So all parallelograms are not rhombuses.
