Describe the slope of the line<br><br> Find the slope.<br><br> m =
spin [16.1K]

Answer:

m = -3/5

Step-by-step explanation:

Since the line is going downwards towards the right, it is a negative slope.

We can use the points to solve for the slope.

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

m = -2 - 1 / 2 + 3

m = -3/5

Therefore, the slope is -3/5.

Find m(angle) ABC<br><br>21 <br><br>132<br><br>48<br><br>19
Brut [27]

I don't like these algebra problems which pretend to be geometry.

These are supplementary angles adding to 180 degrees; geometry done.

7x - 1  + 3x - 9 = 180

10 x = 190

x = 19

ABC=3x - 9 = 3(19) - 9 = 48

Answer 48°

In intrest alone he would've made 1639.09

Step-by-step explanation:

3%= 0.03

  • The first thing you do is multiply $1,500 by the %3 (0.03).

  • When your done multiplying, you should get 45.

  • Add 45 to 1500

  • Now you have 1545

  • Then you repeat the process over, two more times. However the numbers will change.
