Answer:
a=1/3
Step-by-step explanation:
from the point on the graph
x=4 and y=8
substitute them into the equation:
y=a(x-2) (2x+4)
you will get
8=a(4-2) (2(4)+4)
8=a(2) (8+4)
8=a(2) (12)
8=2a×12
8=24a
divide both sides by 24
8/24=24a/24
1/3=a or a=1/3
All you need to do is find the volume of those number
The answer is b) 70 words per minute. If you divide 245 by 3.5, you get 70. So, the answer is 70 words per minute.
Discount prices/the discount
