Answer:3x + 7y = 63
Explanation:The equation of PQ is
y = -(3/7)x + b
To find b, note that the line passes through the point (7,6). Therefore
6 = -(3/7)*7 + b
6 = -3 + b
b = 9
The equation of PQ is
y = - (3/7)x + 9
or
7y = -3x + 63
3x + 7y = 63
Answer: The following that are not produced by a stream are:
1. moraines
2. Floodplain
Explanation: Stream produces:
1. Delta which occurs when streams enter a standing body of water.
2. Alluvial fans occurs when a stream leaves a relatively steep area and enters a nearly flat one.
Answer:May I know what the question is?
Explanation:
Answer: Coagulation and flocculation are often the first steps in water treatment. Chemicals with a positive charge are added to the water. The positive charge of these chemicals neutralizes the negative charge of dirt and other dissolved particles in the water.
Hope this somehow helps!
