Answer:
The answer is 3.4
Step-by-step explanation:
5 or more, round up
4 or less, round down
rounding 6
round up
so...
3.4
(-2, -7) and (-4, -9)
0.5 x 4 = 2 feet / 2 feet in 4 seconds
15 - 2 = 13
New depth: 13 feet
0.4 x 3 = 1.2 feet / 1.2 feet in 3 seconds
13 - 1.2 = 11.8
New depth: 11.8 feet
2x-4y=8
Add 4y to each side to separate the variables, since you want to solve for x let be on the left
2x=4y+8
Divide the entire equation by 2 to allow x to stand alone
x=2y+4
And I have to type some more so it will let me answer the question so here ya go
