Answer:
The inverse is 1/3x -2
Step-by-step explanation:
f (x) = 3x + 6
y = 3x+6
Exchange x and y
x = 3y+6
Subtract 6 from each side
x-6 = 3y+6-6
x-6 = 3y
Divide by 3
1/3x - 6/3 = y
1/3x -2 = y
The inverse is 1/3x -2

Answer:
35
All angles of a triangle = 180 degrees subtract 40 from 180 and you get 140
180-40=140 because the other angles are equal with the same equation to get them divide 140 by 2 140/2=70 then you have to get h alone so you divide by the other 2 in the equation 70/2=35 h=35
The answer is B. (x+9)(x+3)
<span>Answer:
After you've diagrammed the scenario, you can see that a right triangle forms after 200 ft of string had been let out. Now let the angle formed between the string and the horizontal plane be θ (now, the hypotenuse = 200 ft, and with reference to the θ, opposite side = 100 ft)
so we have, sin θ = opp / hyp = 100/200 = 1/2
therefore, θ = 30
now horizontal distance travelled by the kite (again assuming the person flying the kite is still/not moving) or adjacent side = cos θ x hypotenuse = (cos 30) x 200 ft = 173 ft
time elapsed so far = distance / speed = 173 ft / (8 ft/s) = 21.66 secs
rate at which angle is decreasing = total angle covered / time elapsed = 30/21.66 = 1.39 degrees / sec
you may want to convert it to radians if that's what you are looking for. 1.39 degrees/sec = 1.39 x ( π / 180) = 0.024 radians/sec</span>
