  • All angles in a triangle add up to 180°

Step-by-step explanation:

<u>Step 1: Set Up Equation</u>

29° + (4x + 9)° + (x + 17)° = 180°

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Combine like terms:                    5x + 55 = 180
  2. Isolate <em>x</em> term:                              5x = 125
  3. Isolate <em>x</em>:                                       x = 25

Each letter of the alphabet is assigned a numerical value according to its position in the alphabet. Encode the message SEND âHE
SCORPION-xisa [38]

Answer:

<h2>f⁻¹(x) = ∛(x+1)</h2>

Step-by-step explanation:

Given the encoded message defined by the function f(x) = x³-1,  the inverse function that the decoder would need when the message is received can be expressed as thus:

let the inverse of the function be represented as y such that y = x³-1.

Making x the subject of the formula from the equation above;

x³ = y+1

Taking the cube root of both sides:

∛x³ = ∛(y+1)

x = ∛(y+1)

replacing y with x:

y = ∛(x+1)

f⁻¹(x) = ∛(x+1)

The encoded message is the inverse function ∛(x+1)

Can someone help me please will give brainliest
wolverine [178]

Answer:

  see below

Step-by-step explanation:

Each point moves to half its previous distance from P. It is probably easier to count grid squares on the graph than it is to do the math on the coordinates.

If you're doing the math on the coordinates, it is convenient to use P = (0, 0), then multiply each of the coordinates of A, B, and C by 1/2. For example:

  A' = (1/2)A = (1/2)(8, 4) = (4, 2)
