For the first line:

m = (-5 - 0) / (0 - 2.5) = 2

For the second line:

From the given equation,

m = 2

For the third, using the given coordinates (-1,3) (1,7)

m = (7 - 3) / (1 - (-1)) = 2

Therefore, all the slopes of the lines are 2 and none of them have the smallest slope compared to the others.

We have then:

The vertical axis represents the imaginary part.

The horizontal axis represents the real part.

We then have the following number:

-14 - 5i

Since the real part and the imaginary part are negative, then the number is located in the third quadrant of the complex plane.

f(x) = (x + 4) (x + 1) (x + 2)

From the options, (x + 2) is the factor

f(x) / g(x) = (6x3 - 19x2 + 16x - 4) / (x - 2)

This can be solved by factoring the numerator, by synthetic division or using the remainder theorem.

The result is:

The angles can solved by using the cosine law. Solving for the measure of angle A

15² = 20² + 12² - 2(20)(12) cos A

A = 48.35°

Angle B can solved by either also using the cosine law or by sine law. Let's use sine law:

20 / sin B = 15 / sin 48.35

B = 85.06°

The measure of angle C can just be solved by difference of the total angle of the triangle.

C = 180 - 48.35 - 85.06

C = 45.59°

15² = 20² + 12² - 2(20)(12) cos A

**Answer:**

A) Price= 1617*Year - 3.116e+006; B) 150340$ By 2020

**Step-by-step explanation:**

We have a data set of 7 x, y pairs, this data set can be modelled as line, applying a linear regression calculator we found that the trend line can be modelled as Price= 1617*Year - 3.116e+006

Attached you will find the regression results where x is the year variable and Y is the price. If we now plug year=2020 in the equation we have:

Price=1617*2020-3.116e+006 = 150340$

The best answer to the problem given above would be letter A. The speed of the skater travels at 10 miles per hour constantly. I got this through employing the formula, y2 - y1 / x2 - x1 and computed using the points.

which is:

v = (25 miles -10 miles) / (2.5 hrs - 1 hrs)

v = 10 miles per hour

Thus, the answer is 10 miles per hour.

which is:

v = (25 miles -10 miles) / (2.5 hrs - 1 hrs)

v = 10 miles per hour

Thus, the answer is 10 miles per hour.

**Answer:**

D. The expression is . It takes 40 minutes to shape and fire 10 pots.

**Step-by-step explanation:**

Let the number of pots in a batch = p

Now, one pot takes 3 minutes to get in a shape.

Then, 'p' pots will take minutes to get in a shape.

Also, it takes 10 minutes to fire one batch of pots.

**Thus, the expression for the time taken to form one batch of pots = **

So, when number of pots = 10 i.e. p= 10.

Time taken to fire the pots = = 30+10 = 40

**That is, 'It takes 40 minutes to shape and fire 10 pots'.**

Thus, option D is correct.
