Answer:
Slope of line passing through (3,-7) and (-1,1) = -2
Step-by-step explanation:
The slope of a line passing through points (x₁,y₁) and (x₂,y₂) is given by
Here points are given by (3,-7) and (-1,1)
So we have (x₁,y₁) = (3,-7) and (x₂,y₂) = (-1,1)
Slope
Slope of line passing through (3,-7) and (-1,1) = -2

it's me again. Is the answer B?
Step-by-step explanation:
Answer:
0.84
Step-by-step explanation:
Let the probability that a city bus is ready for service when needed is represented as P(ready)=77%=0.77
Let the probability that a city bus is ready for service and has a working radio be represented as P(ready and radio)=65%=0.65
probabilty that it has a working radio given that it is ready for service =
P(radio and ready)=P(ready and radio) ÷ P(ready)
=0.65÷0.77=0.84416
≈0.84 to the nearest tenth
Answer:
the answer is D
8
two negatives make a postive as they cancel each other out
5 - - 3 = 5 + 3 = 8
the only way the answer could be - 2 is if the original question said 5 + - 3 = - 2
Answer:
see below
Step-by-step explanation:
In the attachment, the points are listed in the order given in the problem statement. (They are listed to the right of the "rotation matrix", with x-coordinates above y-coordinates.)
__
I really don't like to do repetitive calculations, so I try to use a graphing calculator or spreadsheet whenever possible. Angles are measured CCW.
As always, the rotation transformations are ...
180° — (x, y) ⇒ (-x, -y)
270° — (x, y) ⇒ (y, -x)
