I will have to say that it has to be D because the 2 is on the y-intercept at positive and if u go over 3 to the left its a negative.this is what I'm applying the answer is
Answer:
The first one
Step-by-step explanation:
<span>erry starts rowing at 2 pm from the west end of the lake, and Tao starts rowing from the east end of the lake at 2:05 pm.
------
Terry DATA:
rate = 60 meter/min ; time = x min ; distance = r*t = 60x meters
-----
Tao DATA:
rate = 40 meter/min ; time = x-5 min ; distance = r*t = 40(x-5) meters
--------------------------
If they always row directly towards each other at what time will the two meet?
------
Equation:
dist + dist = 2000 meters
60x + 40(x-5) = 2000
20x = 1800
x = 90 minutes
---</span>
Since lines a and c are parallel and we are given that c is perpendicular to b, we can infer that b is also perpendicular to a.
So, a and b are perpendicular, the angle formed by these lines should be 90.
Hence, angle 2 is 90.
Hope this helps :)
yea just put a line over the 0 to indicate it's infinite
