If a is the number of events, then a = 1. Plugging in 1 for a in the equation
, you get
.
Total cost is $9.
Answer:
x=-15, y=25. (-15, 25).
Step-by-step explanation:
2x+3y=45
x+y=10
--------------
x=10-y
2(10-y)+3y=45
20-2y+3y=45
20+y=45
y=45-20
y=25
x+25=10
x=10-25
x=-15
<span>8 + 5n = -72
5n = -72 - 8
5n = - 80
n = -80/5
n = -16</span>
The recursive formula can be used to generate the shown sequence
Step-by-step explanation:
Recursive formula is the formula that is used to generate the next term of a sequence using previous term.
The general form of arithmetic sequence's recursive formula is:
Given
5,-1,-7,-13,-19
Here
First of all we have to find the common difference of the sequence.
So,
Putting the value of d in the general recursive formula
Hence,
The recursive formula can be used to generate the shown sequence

Answer:
-37/68
Step-by-step explanation:
3/4(14x+8)-(1/2x+2)=3/8(4-x)-1/4
(21/2x+6)-(1/2+2)=(3/2x-3/8)-1/4
(21/2x-1/2x)+(6-2)=3/2x-3/8-1/4
10x+4=3/2x-5/8
37/8=-17/2x
37/8 (2)=-17/2x(2)
37/4=-17x
37/68=-x
-37/68=x
