Find the slope of the line passing through the points (1, -1) and (4, -2).

Mathematics
1 answer:
vagabundo [1.1K]2 years ago
5 0

Answer:

slope=-\frac{1}{3}

Step-by-step explanation:

To find the slope of the two points (1, -1) and (4, -2) we have to use the slope formula.

slope=\frac{y_{2}- y_{1} }{x_{2} -x_{1} }             slope=\frac{(-2)- (-1)}{4 -1}      

slope=\frac{-1 }{3}=-\frac{1}{3}  can also be written as a decimal  slope=-0.333333

Which transformation of f(x)=3^x does h(x)=-3^x-7 represent?
vaieri [72.5K]
F(x) = 3^x and g(x) = 3^x - 7 => h(x) = f(x) - 7.  This is f(x) has been translated 7 units downward.

If you graph f(x) you can obtain h(x) by shifting the graph of f(x) 7 units downward.

In triangle A B D , the measure of angle A is 10 degree less than the measure of angle B . The measure of angle D is 20 degree m
elixir [45]

Answer:

<u><em>Measure of angle A is 27 7/9 degrees.</em></u>

Step-by-step explanation:

Lets call measure of angle A is <em><u>X-10</u></em>

Lets call measure of angle B is X

Lets call measure of angle D is 2.5X+20

We know that the sum of triangles add up to 180 degrees

X+X-10+2.5X+20=180

X=37 7/9

So measure of angle A is 27 7/9 degrees.

I hope this is right. :)

The temperature fell from 0 degrees to 15 1/2 degrees below 0 in 5 3/4 hours. Wen tried to find the change in temperature per ho
iren2701 [21]

Answer:

-62/23 degrees per hour

Step-by-step explanation:

Do this by dividing the total change in temperature (-15 1/2 degrees) by the total elapsed time (5 3/4 hrs):

-31/2 degrees       -62/4 degrees        Note:  convert 31/2 to 62/4

--------------------- = ------------------------ = -62/23 degrees per hour

23/4 hrs                  23/4 hrs

The relationship of the given angles are:

1. A. Adjacent

2. B. vertical

3. B. vertical

4. E. linear pair

5. C. complementary

6. D. supplementary

7. C. complementary

8. A. adjacent

9. A. adjacent

10. D. supplementary

11. A. adjacent

12. C. complementary.

<h3>How to Determine the Relationship Between Angles?</h3>

Different pairs of angles are related to each other in several ways. The explanation below shows the relationship between the given angles.

1. Angles 2 and 3 share a common vertex and a common side, therefore:

<2 and <3 are: A> Adjacent

2. <3 and <4 are non-adjacent angles that share a common vertex and are opposite each other. Thus:

<3 and <4 are: B. vertical

3. <1 and <3 are: B. vertical

4. <1 and <2 lie on a straight line and are adjacent to each other. Therefore, they are a: linear pair

5. 78 + 12 = 90 degrees. Therefore, their relationship is that they are: C. complementary

6. 123 + 57 = 180. Therefore, they are: D. supplementary

7. Angles a and b form a right angle. Therefore, they are: C. complementary

8. <1 and <2 are: adjacent

9. <3 and <4 are: A. adjacent

10. 90 + 90 = 180, therefore, the angles are: D. supplementary

11. Both angles are: A. adjacent

12. 40 + 50 = 90 degrees. Therefore, the angles are: C. complementary.
