Answer:

-7x + 6 = x² - 7x

-7x + 7x +6 - x² = 0

0 + 6 - x² = 0

-x² + 6 = 0

-x² = (-6)

x² = 6

x = ±√6

x =√6 or x = -√6

Answer:

x = √6 or - √6

Step-by-step explanation:

equation: -7x + 6 = x² - 7x

switch sides:

x² - 7x = -7x + 6

Add 7x to both sides,

x² - 7x + 7x = -7x + 7x + 6

x² = 6

For x² = f(a) the solution are x = √f(a), -√f(a)

x = √6 , x = - √6

Given f(x) = x^2 + x − 2 and g(x) = 2x − 4, identify (f + g)(x).

shutvik [7]

Answer:

(f + g)(x) = x^2 + 3x - 6

Step-by-step explanation:

Given f(x) = x^2 + x − 2 and g(x) = 2x − 4

Plug in:

(f + g)(x) = x^2 + x − 2 + 2x − 4

(f + g)(x) = x^2 + 3x - 6

Name a point that is not coplanar with points A, B, and C.

boyakko [2]

Points are coplanar if they are located on the same plane. A plane is one of the undefined terms in geometry. It is described as a flat surface in a two-dimensional area. If you look at the given figure, find points that are not included in the shaded plane of points A, B and C. That would be point M or point D.

Find the value of x in each triangle. Please help me <33

frozen [14]

Answer:

x = 11

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

sum the 3 angles and equate to 180

5x + 4 + 6x - 3 + 4x + 14 = 180 ← collect like terms on left side

15x + 15 = 180 ( subtract 15 from both sides )

15x = 165 ( divide both sides by 15 )

x = 11
