Answer: D
Step-by-step explanation:
Lets go equation by equation.
A) Is an upside down parabola shifted up 2 units. It will have to go downwards so its range is not greater than 2 (it is actually y < 2).
B) This is your regular old parabola, moved up two and shifted right 1. This means that since the graph is shifted up two, it will be y >= 2 (because the lowest point will be at y = 2).
C) This is a line shifted up 8 with a slope of 2. This will definitely go to infinity in both directions so it doesn't have a limited range.
D) This is an exponential graph shifted up two units. It will go beyond y = 2 and up to infinity. So, its range is y >2.
Answer:
Paige, 10 3/4
Step-by-step explanation:
To figure out this problem, first you would want to get the total amount of time each girl spends on lessons. Since Paige does lessons 5 days a week for 2 1/4 each day, you would multiply 5 and 2 1/4. This equals 11 1/4 hours.
For Maggie, you would need to multiply 2 times 1/4. This equals 1/2 hours.
Paige spends more hours on lessons. She spends 10 3/4 more hours than Maggie.
Answer:
Here is what I think the answer is.
n+2n+8 = 5n-10
3n+8 = 5n-10
-8 -8
3n = 5n-18
-5n -5n
-2n = -18

-2 -2
n = 9

Answer: 8 : 19
Step-by-Step Explanation:
No. Of Boys = 8
No. Of Girls = 11
Total No. Of Students = 19
Ratio of Boys to Total Students
= 8/19
=> 8 : 19
8! = 8 x 7 x 6 x 5 x 4 x 3 x 2 = 40320.
