K is the constant of proportionality also the same as slope.
You can see the commonality in the equations
y = kx
y = mx + b
The difference is that is a direct proportion the line will always go through the origin so the b will be zero.
The answer is B.
Answer:
9 games
Step-by-step explanation:
If he purchase 1 game, he spent $12.50. If he purchased 2 games, he spent 2(12.50) = $25.
This means he spent 12.5x for x number of games.
His total spending will be 12.5x + 20. He has $17.50 left on the card from $150.
150 - (12.5x + 20) = 17.5
150 - 12.5x -20 = 17.5
130 - 12.5x = 17.5
-12.5x = 17.5 - 130
-12.5x = -112.5
x = 9

The formula of the future value of annuity due is
Fv=pmt [(1+r/k)^(kn)-1)÷(r/k)]×(1+r/k)
Fv future value 1250675
PMT semiannual payment?
R interest rate 0.045
K compounded semiannual 2
N time 30 years
Solve the formula for PMT
PMT=Fv÷ [(1+r/k)^(kn)-1)÷(r/k)]×(1+r/k) Plug in the formula
PMT=1,250,675÷((((1+0.045
÷2)^(2×30)−1)÷(0.045÷2))×(1+0.045÷2))
=9,828.44...Answer
Hope it helps!
