3/8 should be your answer !!!
Answer:
Step-by-step explanation:
- Let the speed of the boat be x
- Speed against the current in the river is x - 2
<u>Time in the river:</u>
<u>Time in the lake:</u>
<u>The difference:</u>
Solve for x to find the speed of the boat
<u>Multiply both sides by x(x - 2) to clear the fraction:</u>
- 6x = 15(x - 2) - x(x - 2)
- 6x = 15x - 30 - x² + 2x
- x² - 11x + 30 = 0
- (x - 5)(x - 6) =0
- x -5 = 0, x - 6 = 0
- x = 5 km/h, x = 6 km/h
Answer:
-2x+29 is the answer to this question
Answer:
<h3>
(f o g) (x) = 2x² - 13</h3>
Step-by-step explanation:
f(x) =2x+1 and g(x)=x²-7
(f o g) (x) = f [g(x)] = 2[g(x)] + 1 = 2(x²-7) + 1 = 2x² - 14 + 1 = 2x² - 13
