Answer:
1/2 or .5
Step-by-step explanation:
solve for x in the bottom equation
x = 4 - 8y
substitute the equation for x back into the top equation
4(4- 8y) - y = 3y + 7
solve for y
36y = 9
y = 1/4
substitute y back into the equation solving x
x = 4 - 8(1/4)
solve for x
x = 4 - 2
x = 2
xy = 1/4 * 2
xy = 1/2
Answer:
The answer is b
Step-by-step explanation:
Hello there! So the speed goes up in 6 seconds, maintains for 8 seconds, and then holds for 20 seconds. When something is resting, the line stays straight horizontally for that 20 seconds. B and C are eliminated, because there is no break for C and B does not show the speed accurately. Really, the fish would speed up to 2.5 m/s in 6 seconds, then it maintains that speed, and slows down. D shows a constant speed, which the speed isn't constant, so D is out. A is the only one that represents the scenario properly. The answer is A.
