A line’s equation is given in point-slope form:
Veronika [31]

Answer:

Slope: -3, apparent point: (-1, -2)

Step-by-step explanation:

Point-slope form means the equation of a line is given in the form of y - y1 = m(x - x1), where x1 and y1 are coordinates of a point that lies on the line and m is its slope. Keeping this in mind while looking at the given equation, you can see that -3 is where m goes, meaning the slope is -3. You can also see that 1 and 2 are in the places where - x1 and - y1 go (don't forget those minus signs!) so you take those two and make them an ordered pair for your apparent point of (-1, -2).

What’s the explanation
Viktor [21]

Answer:

x³ + 2x² - 19x - 20

Step-by-step explanation:

x + 1 = 0

x = -1

Substitute x = (-1) in the polynomial

x³ + 2x² - 19x - 20 = (-1)³ + 2*(-1)² - 19 *(-1) - 20

                            = -1 + 2 +19 - 20

                             = -1 - 20 + 2 + 19

                              = -21 + 21 = 0

So, (x + 10 ix a factor of  x³ + 2x² -19x - 20

KATRIN_1 [288]

Answer:

24.49 units

Step-by-step explanation:

It si NOT a right triangle, so you'll have to use law of sines

angle C = 180 - 45-75 = 60 degrees

30 / sin60 =  AC / sin 45

AC = 30 * sin 45 / sin 60 = 24.49 units
