If Dan is 8x years old next year then he must be 8x-1 years old this year
With the same logic, five years ago from this year, he must be 8x-1-5=8x-6

The answer should be 8x-6

NEED SOMEONE TO CHECK AND TELL ME C

erik [133]

Part A:
f(x)=30(1.2)^x
f(x)=45+3x

Part B: Neighborhood A is 74.6496, so that rounds to 75 homes, and Neighborhood C is exactly 60 homes

Part C:
i would graph them in a graphing calculator, and use the functions to see where the 2 lines intersect.

The x value for when they intersect (# of years) is 3.3207883, so approx. 3.3 years for them to be equal

In the scale used on a blueprint, 14 inch represents 3 feet. On the blueprint, what is the length of a room with an actual lengt

VashaNatasha [74]

Answer: 2in

Step-by-step explanation:

Hi, to answer this question we have to apply proportions:

The correct scale on the blueprint is : 1/4 inch represents 3 feet.

So, the proportion is: 1/4 inch/ 3 feet = (1/4) /3

For 24 feet:

x inches /24 feet = x/24

So:

(1/4)/3 = x/24

Solving for x (inches)

[(1/4)/3 ] (24) =x

x =2 inches

Use the future value formula to find the indicated value. FV = $ 5330 n=24; i=0.08; PMT=? PMT=$ (round to the nearest cent)

spin [16.1K]

Hi there
The future value formula is
Fv=pmt [(1+r)^(n)-1)÷r]
Solve the formula for PMT
PMT=Fv÷[(1+r)^(n)-1)÷r]
So
PMT=5,330÷(((1+0.08)^(24)−1)÷(0.08))
PMT=79.83

Good luck!
