Answer:
= 2n²
Step-by-step explanation:
From the sequence 2,8,18,32,50
The difference between each numbers are
: 6, 10, 14, 18
The difference between the second sequence is 4.
Therefore the nth term of the sequence is 2n²
Answer:
50 rooms with kitchen facilities and 100 rooms without kitchen facilities
Step-by-step explanation:
Let the rooms without kitchen facilities be x and those with kitchen facilities be y
Form set of equations
Since the total rooms are 15, then the first equation is
x+y=150
Therefore, x=150-y
Considering the cost of rooms and what was collected, then
80x+100y=13000
Substituting x with 150-y then
80(150-y)+100y=13000
12000-80y+100y=13000
20y=1000
Therefore, x=150-y=150-50=100 rooms
Therefore, there are 50 rooms with kitchen facilities and 100 rooms without kitchen facilities
Answer: 73
Step-by-step explanation:
You use the bowtie method to get the answer for this problem. This is where you do 4/15 and x/273. You multiply 4 by 273 and x by 15. Resulting in the answers 1092 and 15x. To find the value of x, you divide 1092 by 15. and get 72.8. I rounded up to 73.
The slope of the line that represents the relationship is 1.3
The equation is 1.3x
At x = 10, y = 13 and at x = -10, y = -13.
