750 bikes would be sold for $350
Let x represent the number of bikes sold per month and y represent the price.
550 bikes are sold at a price of $250, this can be represented by (550, 250). Also, 750 bikes is sold at a price of $150, hence it is represented by (750, 150)
A linear function is represented by:
y = mx + b
m is the slope, b is the y intercept.
Therefore the function is:
The number of bikes sold for $350 is:
350 = (1/2)x - 25
x = 750
Therefore 750 bikes would be sold for $350

Answer:
Step-by-step explanation:
In the rectangular complex number -9√3 + 9i, which has a standard form a + bi, the a = -9√3 and the b = 9. We need this in polar form (r, θ) where
and filling in:
(notice we do not put the i in there with the 9).
so
r = 18. Now let's move on to the angle, which is a little more difficult. The angle is found in the inverse tangent ratio:
so filling that in, we have:
Since tangent is the side opposite over the side adjacent, y is positive and x is negative in the second quadrant. This is a 30 degree angle in QII, which has a reference angle of 150 degrees. This angle in radians is 
, so the polar form of that number is (18, 
)
Answer:
282ft^3
Step-by-step explanation:
The outer box is: 9 x 6 x 8=432
The inner box is: 5 x 5 x 6= 150
432-150=282ft^3
Answer:
1/19( -171 - 10√5 + 40√30)
Step-by-step explanation:
Probably the best way to do this would be to mutiply each fraction ( top and bottom) by the conjugate of the denominator. This would then give a denominator with no radicals.
So 2√5 / √6 + 5 wil be multiplied by (5 - √6) / (5 - √6)) to give
(10√5 - 2√30)/ (25 - 6).
= 2√5 (5 - √6) / 19
Do the same with th other 2 fractions and the simplifuication will be a lot easier.
I did this and got 1/19( -171 - 10√5 + 40√30)
