Step-by-step explanation:
2/3=10/15 (divide 15 by 3 to get 5, then multiply both numerator and denominator by 5 to set equivalent)
3/5=9/15
10/15 is greater than 9/15, so during the 1st week there were more boy campers
Answer:
- recursive: a[1] = 7440; a[n+1] = a[n] -120
- explicit: a[n] = 7440 -120(n -1)
Step-by-step explanation:
The sequence of amounts in Jackson's account will be ...
7440, 7320, 7200, ...
with a first value (a1) of 7440 and a common difference (d) of -120.
The recursive formula for an arithmetic sequence is ...
a[1] = a1
a[n+1] = a[n] +d
For our sequence, the recursive formula is ...
a[1] = 7440
a[n+1] = a[n] -120
__
The explicit formula for an arithmetic sequence is ...
an = a1 +d(n -1)
For our sequence, the explicit formula is ...
a[n] = 7440 -120(n -1)
Answer:
Think about what domain and range is. Domain is the x and range is the y.
Step-by-step explanation: What values of x can you put in this function? Is there any number you cannot use?? Then what y's will you get back? The best way to find out might be to graph it to look. Since it is an even function whose ends go up, all the y's will be greater than or equal to the y value of the vertex.
Three times the result of a number plus a number equals two times a number minus a number.
or
Three times the result of a variable plus a variable equals two times a variable minus a variable.
Answer:
5/12
Step-by-step explanation:
Divide both numbers by the least common multiple. In this case it's 5.
25/5=5
60/5=12
