Mathematics

3 0

Answer:

cos=1

Step-by-step explanation:

Use the acronym SOH-CAH-TOA

sin = \frac{3}{4}

So opposite is 3 and hypotenuse is 4.

tan = \frac{-3}{4}

So opposite is -3 and adjacent is 4.

cos = adjacent/hypotenuse

cos = \frac{4}{4}=1

Which of the following values for x and y make the equation 4x+2y+3=19 true?
Aleksandr-060686 [28]

Answer:

x = 3, y = 2

Step-by-step explanation:

Substitute the values of x from each alternative in the previous <em>question</em>, then solve for y. This is depicted below.

  • <em>A. y = -7, x = 5, 4(5) + 2y + 3 = 19</em>
  • <em>B. y = 0 and x = 4, 4(4) + 2y + 3 = 19</em>
  • <em>C. y = 2 and x = 3, 4(3) + 2y + 3 = 1</em>
  • <em>D. y = 4, x = 2, 4(2) + 2y + 3 = 19</em>

Only the third option has a y value that is <em>comparable</em> to the value in the computations, according to the calculations.

As a result, the letter C is the correct response.
