Y = -√(x + 3) + 4
y = -√(x + 3)² + 4
y = -(x + 3) + 4
y = -x - 3 + 4
y = -x + 4
y = x - 4

The width of a deck is 5 feet shorter than its length. The equation that represents this situation is y = x – 5. What does x rep
ollegr [7]

X represents the length of a deck. There are three parts to this equations. The 1. width, 2. the length, and 3. the 5 feet shorter. Using the key words, y = the width of a deck (uses the term is which means =) So that takes the width part out of the equation. Then, 5 feet shorter means -5 than a number. That takes away the 5 feet shorter part of the equation. That leaves x to equal the length of the deck.

Does anybody know the correct answer to this?
olganol [36]

Answer:

  • sin(X) = 4/5
  • cos(X) = 3/5
  • tan(X) = 4/3

Step-by-step explanation:

The mnemonic SOH CAH TOA is intended to help you remember the relations between sides and trig functions in a right triangle.

  Sin(X) = Opposite/Hypotenuse = 24/30 = 4/5

  Cos(X) = Adjacent/Hypotenuse = 18/30 = 3/5

  Tan(X) = Opposite/Adjacent = 24/18 = 4/3

_____

You may be expected to leave the trig ratios in the original unreduced form.
