Mathematics
1 answer:
Molodets [167]3 years ago
6 0

REASONS:-

1ST STEP

6x + 7 = 8x - 17

GIVEN LHS = RHS

2ND STEP

7 = 2x - 17

Bez +ve 6x when move to another side will change to -ve so it reduces 8x to 2x

3RD STEP

24 = 2x

Bez -ve 17 when move to another side will change to +ve so it increases 7 to 24

4TH STEP

12 = x

Bez 2 in multiplication when move to another side will change to division so it reduces 24 to 12

5TH STEP

x = 12

it the answer we obtained after solving

Write a two-column proof. Given: line BD bisects angle CBE. Prove: angle ABD approximately equal to angle FBD.
ale4655 [162]

Answer:

The proof is derived from the summarily following equations;

∠FBE + ∠EBD = ∠CBA + ∠CBD

∠FBE + ∠EBD = ∠FBD

∠CBA + ∠CBD = ∠ABD

Therefore;

∠ABD ≅ ∠FBD

Step-by-step explanation:

The two column proof is given as follows;

Statement {}                                       Reason          

\underset{BD}{\rightarrow} bisects ∠CBE {}                            Given

Therefore;

∠EBD ≅ ∠CBD  {}                              Definition of angle bisector

∠FBE ≅ ∠CBA {}                                Vertically opposite angles are congruent

Therefore, we have;

∠FBE + ∠EBD = ∠CBA + ∠CBD {}     Transitive property

∠FBE + ∠EBD = ∠FBD {}                    Angle addition postulate

∠CBA + ∠CBD = ∠ABD {}                   Angle addition postulate

Therefore;

∠ABD ≅ ∠FBD        {}                          Transitive property.

Answer:

  • x = 2 and x = 5

Step-by-step explanation:

<u>Given functions:</u>

  • f(x) = x² - 6x + 8
  • g(x) = x - 2

<u>Fill in the table by calculating each value of f(x) and g(x)</u>

  • x  >>> f(x)  >>> g(x)
  • 0 >>>  8    >>> - 2
  • 1  >>>  3    >>>  - 1
  • 2  >>>  0   >>> 0              equal
  • 3  >>>  - 1  >>> 1
  • 4  >>>  0   >>> 2
  • 5  >>>  3   >>> 3              equal
  • 6  >>>  8   >>> 4
