Let's call dimes x and the quarters x+3 since we have 3 more of them.
x+x+3=45
2x=42
x=21
we have 21 dimes and 23 quarters
21*0.10=2.1
23*0,25=5.98
if we add those together it equals 8.08
Answer:
Step-by-step explanation:
The equation is y = -4x²
Next time, please share the answer choices.
Here's a short table of possible solutions:
x -x² (x, y)
----- ------ ---------
0 0 (0, 0)
2 -4 (2, -4)
-3 -9 (-3, -9)
I believe it would be either 0 or 1 but im not entirerly sure
C is the answer. Adding all the "x" values would give 0, therefore, no solution
Since it's paid quarterly, then the yearly interest of 2.8% should be divided by 4.
Since the payment is I/4th of the year, then the number of payment will 4 times more:
A= P(1+i)ⁿ, and for a period of 4, A = P(1+i/4)⁴ⁿ
A=5500(1+0.028/4)⁴ˣ⁴ = 5500(1+0.028/4)¹⁶ = $6149.42 (answer A)
