So, first let's convert 3 minutes into seconds. We get that 3 min = 180 seconds.

Now, it says that the treasure sinks 20 feet per second and we want to know if it will reach -4,200 feet before 180 seconds. So, one way we can solve that it multiply 180 times 20.

We get 3,600 which means that in 3 minutes, the treasure will be -3,600 feet deep. The treasure will NOT reach the ocean floor in less than 3 minutes.

Hope this helps!

____ [38]

Answer:

The answer is "(5, -6)"

Step-by-step explanation:

Given:

The Pre-image line at point B is: (3, 4)

Solution:

$\ rx-axis \circ \ T2,2 (3,4) \\\\\Rightarrow \ rx-axis \ ( T2,2 (3,4) )\\\\ \Rightarrow \ rx-axis ( 5,6 ) \\\\ \Rightarrow (5, -6)\\$

The coordinates of B point is (5,-6).

Solve and check:8a-4=25+6(a-8)

OlgaM077 [116]

8a - 4 = 25 + 6 (a - 8)

(distribute the 6)

8a - 4 = 25 + 6a - 48

(combine like terms 25 - 48)

8a - 4 = 6a - 23

( subtract 6a from both sides)

2a - 4 = -23

(add 4 to both sides)

2a = -19

(divide both sides by 2)

a = - 9.5

////CHECK/////

8 (-9.5) - 4 = 25 + 6 ( -9.5 -8)

(plug each side into a calculator)

-80 = -80

FINAL ANSWER:

a = -9.5
