Answer:
x = 2
y = -1
Step-by-step explanation:
2x + y = 3
-2y = 14 - 6x
6x - 2y = 14
2x + y = 3 | ×3 |
6x - 2y = 14 | ×1 |
6x + 3y = 9
6x - 2y = 14
__________--
5y = -5
y = -5/5
y = -1
2x + y = 3
2x + (-1) = 3
2x = 3 + 1
2x = 4
x = 4/2
x = 2
Answer:
5,310
Step-by-step explanation:
6% of 4,500 is 270
270×3 is 810
810+4,500=5,310
For possible roots I got...
1
1/3
5
5/3
Not really sure about a b c or d.
x = -0.76508126
Volume of cuboid =l×b×h
area of base of the cuboid =l×b
hence
volume of cuboid is = area of base × height
140=88×h
h=140÷88
h=5
The recursive formula is
= 14;
=
+ 3
The explicit formula is 
Step-by-step explanation:
The recursive formula of the nth term of the arithmetic sequence is
= first term;
=
+ d, where
is the first term in the sequence
is the nth term in the sequence
is the term before the nth term - n is the term number
- d is the common difference.
The explicit formula of the nth term of the arithmetic sequence is
, where
is the nth term in the sequence - a is the first term
- n is the term number
- d is the common difference
∵ The arithmetic sequence is 14, 17, 20, 23, 26
∴ The first term is 14
∵ 17 - 14 = 3
∴ The common difference is 3
∵ The recursive formula is
= first term;
=
+ d
∵
= 14
∵ d = 3
∴
= 14;
=
+ 3
The recursive formula is
= 14;
=
+ 3
∵ The explicit formula is 
∵ a = 14
∵ d = 3
∴ 
- Simplify the right hand side
∴ 
- Add like terms
∴ 
The explicit formula is
