What is the equation of a line that passes through the point (5, −4) and is parallel to the line whose equation is 2x + 5y = 10?
Artyom0805 [142]
A quick way to solve this problem involves copying the given equation:

2x + 5y = 10

dropping the final 10, and
substituting the given x and y values:  (5, -4).  

Then:

2(5) + 5(-4) = C           C = 10-20 = -10

Thus, the equation of this new, parallel line is 2x + 5y = -10.

4. What are the values of the variables in the triangle below? If your answer is not an integer, leave
pentagon [3]

Using relations in a right triangle, it is found that the values of the variables in the triangle below are given by:

x = 18, y = 6\sqrt{3}

<h3>What are the relations in a right triangle?</h3>

The relations in a right triangle are given as follows:

  • The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.
  • The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.
  • The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.

In this problem, the hypotenuse is of 12\sqrt{3}, while the opposite angle to side y is of 30º, hence:

\sin{30^\circ} = \frac{y}{12\sqrt{3}}

\frac{1}{2} = \frac{y}{12\sqrt{3}}

y = 6\sqrt{3}

The adjacent side to the angle of 30º is of x, hence:

\cos{30^\circ} = \frac{x}{12\sqrt{3}}

\frac{\sqrt{3}}{2} = \frac{x}{12\sqrt{3}}

2x = 36

x = 18
