Answer:
C. 1/3x + 5
Step-by-step explanation:
Plugging in the values for x, we get:
y = 1/3(0) + 5 = 5
y = 1/3(6) + 5 = 7
y = 1/3(12) + 5 = 9
y = 1/3(15) + 5 = 10
I almost broke my neck trying to read this problem. :(
The formula of the present value of an annuity ordinary is
Pv=pmt [(1-(1+r/k)^(-kn))÷(r/k)]
Pv present value 280000
PMT monthly payment?
R interest rate 0.06
K compounded monthly 12
N time 20 years
Solve the formula for PMT
PMT=pv÷[(1-(1+r/k)^(-kn))÷(r/k)]
PMT=280,000÷((1−(1+0.06÷12)^(
−12×20))÷(0.06÷12))
=2,006.01
You could divide 100 by 4 which is 25. Then divide 69 by 4 which would bring you to 17.25. 169 divided by 4 is 42.25. The answer would be 42 with a remainder of 1
X= be coffee
Y=be donuts
Set up equations
10x+5y=16.50
5x+10y=14.25
Now multiply first equation by -2 to get a negative
(-2)10x+5y(-2)=16.50(-2)
-20x-10y=-33
Now put both equations to solve for x
-20x-10y=-33
5x+10y=14.25
___________
-15x. = -18.75
Now divide -15 bith sides to get x alone
X= -18.75/-15
X= 1.25
The cost of each coffee cup$1.25
try this for answer (11×3.5)-9=x
