write the equation of the line that passes throughout (-1,5) and has a slope of 3 in point-slope form
SpyIntel [72]
The point-slope form is:
y - k = m(x-h)

So, here, you just plug in values:
y - 5 = 3(x+1)

It would be + 1 because remember, the '-' sign just means the opposite of, not subtraction in this case. Also, m = slope.

Angle 3 and Angle 6 are alternate interior angles. If angle 3 is (3x-5) degrees and angle 6 is (5x-25), what is the value of x?
Nataly [62]

Answer:

  • x = 10

Step-by-step explanation:

<u>Alternate interior angles measure same as per their property:</u>

  • m∠3 = m∠6
  • 3x - 5 = 5x - 25
  • 5x - 3x = 25 - 5
  • 2x = 20
  • x = 10

Which angle has a sine of −12 and a cosine of −3√2 ? A 7π6 B 4π3 C 5π6 D 5π3
kobusy [5.1K]

Answer:

A. 7π/6.

Step-by-step explanation:

I think you mean a sine of -1/2  and cosine of -√3/2   ( the values in the question are not possible)

Angle  π/6 has a sine of  1/2 and a cosine of √3/2  ( from the 30-60-90 triangle).

This angle must be in the third quadrant because the sin and cos are negative.

So the answer is π +π/6 = 7π/6.
