Answer:
Step-by-step explanation:
(0,2) (3,0)
(0-2)/(3-0)= -2/3
the perpendicular slope is 3/2
Easy, they both add up to 180 degrees.
2a-9+5a+14=180
7a+5=180
7a=175
a=25
Answer:
I have to pay 20% of the regular price.
Step-by-step explanation:
Let the regular price of the item is $x.
Now, I have to pay 25%, if the regular price of the item was 20% taken off the regular price.
So, the price of the item after the 20% price is taken off the regular price is 
.
So, I have to pay 25% of that price, i.e. 
Now, if I have to pay y% of the regular price, then
(Given)
⇒ y = 20%
Therefore, I have to pay 20% of the regular price. (Answer)
<h3>
Answer: Choice D) S</h3>
Explanation:
The flat horizontal portion S is where the distance (y) does not increase or decrease. So Ted is stationary during this time frame.
In terms of speed, we would say speed = distance/time = (change in y)/(change in x). Note how this is the slope.
Rise = 0 because the horizontal line does not go up or down. The run is any positive number, though convention usually has Run = 1. Therefore, slope = rise/run = 0/1 = 0. All flat horizontal lines have a slope of 0 to indicate no upward or downward movement.
