Answer:
Your solution is (-3,0)
Step-by-step explanation:
Hi,
We know what Y is, so we can plug it into the second equation.
2x + y = -6
2x + (x + 3) = -6
Now, add the like terms...
3x + 3 = -6
3x = -9
x = -3
Now, plug x back in to find y.
y = x + 3
y = (-3) + 3
y = 0
Your solution is (-3,0)
Hope this helps :)
Let me help you with that :)
2x - 4 = - 10 + x (we transfer the x from the right side, and transfer the - 4 from the left side)
2x - x = - 10 + 4 (we calculate this)
x = -6
And that is the answer; x = - 6 :)
B. 18.37
1990 - 1960 = 30 = t
Plug in the variable "t" to the equation and solve.
P (t) = 18.37
Answer:
Step-by-step explanation:
P = 3,000
r = 5% = 0.05
t = 9 years
Amount after 9 years is
A = P (1+ r)^t
A = 3,000(1+ 0.05)^9 = 3,000 * 1.05^9 = 4653.984648 ≈ $4,653.98
The balance after 9 years, rounded to the nearest cent is
$4,653 and 98 cents
