Answer:
Therefore the solutions are
Step-by-step explanation:
Given:
.........( 1 )
................( 2 )
To Find:
x = ?
y = ?
Solution:
Substituting ' y ' in Equation 1 we get
Using identity (A+B)²=A²+2AB+B² we get
Now Substitute x =0 in equation 2 we get
Or
Now Substitute x =-4 in equation 2 we get
Therefore the solutions are
Answer:
x = 2 | y = 3. ( 2,3 )
Step-by-step explanation:
2(3x + 3y = 15)
6x + 6y = 30
3(4x + 2y = 14)
12x + 6y = 42
- 6x. -6y. -30
6x = 12
÷ 6. ÷6
x = 2
3x + 3y = 15
3(2) + 3y = 15
6 + 3y = 15
-6. -6
3y = 9
÷3. ÷3
y = 3
The formula is
A=p (1-r)^t
A future value?
P current value 42000
R rate of decreases 0.08
T time 6 years
A=42,000×(1−0.08)^(6)
A=42000 (0.92)^6
A=25,466.91 round your answer to get 25467
Hope it helps!
