Answer:
Step-by-step explanation:
n = 3
3(n + 2) = 3(3+2) = 3*5 = 15
There are 62 dimes and 44 nickels.
N + D = 106 (There are 106 coins in all.)
1 nickel = 5 cents.
1 dime = 10 cents.
5*N + 10*D = 840 ($8.40 = 840 cents)
N + D = 106 -------(1)
N = (106 - D)
5*N + 10*D = 840 ---------(2)
5*(106-D) + 10*D = 840
530 - 5*D + 10*D = 840
5*D = 840 - 530
5*D = 310
D = 310/5 = 62
Eq(1) N + D = 106
N + 62 = 106
N = 106 - 62
N = 44
Answer:
6
Step-by-step explanation:
From the blue graph of f(x) we can see that the function value is -6 when x = 6. Similarly, g(5) = -5.
Then: 4*f(6) - 6*g(5) becomes:
4*(-6) - 6*(-5), or
-24 + 30 = 6
X + 1 < 5
x < 5 - 1
x < 4
u basically solve it like equations except for one important rule....with inequalities, when u multiply/divide by a negative number, the inequality sign changes directions. But we didn't have to deal with that rule in this particular problem
Answer:
1.5%
Step-by-step explanation:
According to the Taylor rule, the federal funds rate targeted by the Fed is:
Where AI is the actual inflation (1%), DI is the desired inflation (2%) and PD is the deviation from potential (2%):
The Fed should target a federal funds rate of 1.5%.
