Answer:
The water level is falling.
The initial level of water in the pool was 3,500 units
The water was 2,600 units high after 4 hours.
Step-by-step explanation:
The given function that models the water level is
where 
represents time in hours.
The function represents a straight line that has slope 
Since the slope is negative, it means the water level is falling.
The initial level of water in the pool can found when we put 
into the function.
, hence the initial level is 3,500.
To determine the level of water in the pool after 14 hours, we put 
into the equation to get;
To determine the water level after 4 hours we put 
Answer:
19
Step-by-step explanation:
5 + 4^2 - 6/3
= 5 + 16 - 2
= 21 - 2
= 19
Answer:
<h2>48</h2>
Step-by-step explanation:
(1)
apple × apple × 2apple = 54
2apple³ = 54 <em>divide both sides by 2</em>
apple³ = 27 → apple = ∛27
apple = 3
(2)
apple + apple × green_apple = 24 <em>substituite apple = 3</em>
3 + 3 × green_apple = 24 <em>subtract 3 from both sides</em>
3 × green_apple = 21 <em>divide both sides by 3</em>
green_apple = 7
(3)
strawberry - bannana - banana = 0 → strawberry = 2banana
(4)
strawberry + banana + cherry = 24 <em>substitute from (3)</em>
2banana + banana + cherry = 24
3banana + cherry = 24
(5)
apple + banana - cherry = -1 <em>substitute apple = 3</em>
3 + banana - cherry = -1 <em>subtr3 from both sides</em>
banana - cherry = -4
Add both sides of (4) and (5)
3banana + cherry = 24
<u>+banana - cherry = -4 </u>
4banana = 20 <em>divide both sides by 4</em>
banana = 5
Substitute it to (4):
3(5) + cherry = 24
15 + cherry = 24 <em>subtract 15 from both sides</em>
cherry = 9
Substitute to the last equation:
3 + 5 × 9 = 3 + 45 = 48

Answer:
x = -14
Step-by-step explanation:
Let's solve your equation step-by-step.
4x + 188 = 6x +216
Subtract 6x from both sides:
4x + 188 - 6x = 6x + 216 - 6x
-2x + 188 = 216
Subtract 188 from both sides:
-2x + 188 - 188 = 216 - 188
-2x = 28
Divide both sides by two:
