Answer:
37 I. wlice is the eight answer
Answer:
D
Step-by-step explanation:
Quadratic has a general form of:
The quadratic given here is:
Matching it with the general form, we can see that:
a = 1 [coefficient of x^2]
b = 3
c = 1
Now, if we look at the formula for axis of symmetry, we can easily solve this out. The axis of symmetry is given by:
Axis of Symmetry is
We know a = 1 and b = 3, so we have:
Hence,
D is the correct answer.
Answer:
Step-by-step explanation:
If the speed is constant for 5 machines and produces x amount of toys we know that rate is defined as a constant per time:
Here the machines are constant and the rate is x toys per hour:
If 5 machines make x per hour:
Rate is x/1 hour
The the ratio of 8/5 is 1.6. Therefore for 8 machines the rate is 1.6 times more per hour than for5 machines. Therefore we can write an expression as:
Rate for 5 machines is x and for 8 machines is y:
Answer:
114.75
Step-by-step explanation:
- 6x3=18
- 8x10=80
- 8.5
- Add all together, you get = 229.5
- Divided by 2 you get = 114.75
