1/4, always the number in front of the parentheses when written in point slope gorm
Answer: Lena saved up $3,475 in 25 weeks
Step-by-step explanation:
150 + 532 = 682
682/4 = 133
133 x 21 = 2,793
2,793 + 682 = 3,475
Hope this helps :)
Since there is a common difference of one, this is an arithmetic sequence of the form a(n)=a+d(n-1) which in this case is:
a(n)=15+1(n-1)
All arithmetic sequences have a sum which is equal to the average of the first and last terms time the number of terms, mathematically:
s(n)=(2an+dn^2-dn)/2 (that is just the result of ((a+a+d(n-1))(n/2)) )
Since a=15 and d=1 this becomes:
s(n)=(30n+n^2-n)/2
s(n)=(n^2+29n)/2 so
s(10)=(100+290)/2
s(10)=195 logs
Answer:
4x + 2y
Step-by-step explanation:
We multiply the price of 1 pencil by 4 to get price of 4 pencils plus the price of 1 rubber times 2.

Step-by-step explanation:
there must be something missing here (I guess, the graph).
because just by looking at the 2 points, all 4 answer options could be wrong, or all 4 could be right.
just basing on the point coordinates I see the functional values (y) go from 2 to 4.
but we have no clue about what that curved function does in between these 2 points.
please provide the full information.
