Solve 2w^2– 16w = 12W – 48 by factoring. Select the solution(s)
UkoKoshka [18]

Answer:

w=12 or w=2

Step-by-step explanation:

2w^2-16w=12w-48

2w^2-28w=-48

2w^2-28w+48=0

2(w^2-14w+24)=0

2(w-12)(w-2)=0

(w-12)(w-2)=0

w=12 or w=2

Dima020 [189]

Answer:

  • 1700: $50
  • 2000: $60
  • 7000: $90

Step-by-step explanation:

You can read the answers from the graph. Find the usage on the horizontal scale, and look at the vertical scale to find the corresponding charge.

__

<h3>1700 gallons</h3>

The value 1700 is between 1000 and 2000, so will be between 1 and 2 on the horizontal scale. The graph is flat in that region. The charge is $50.

__

<h3>2000 gallons</h3>

The graph has a jump at 2 on the horizontal scale. The solid dot tells you that the charge is $60.

__

<h3>7000 gallons</h3>

At 7 on the horizontal scale, the graph is increasing from 80 to 100. At 7000 gallons, the line passes through the grid intersection indicating the charge is $90.

I = $ 1,200,000.00

Equation:

I = Prt

Calculation:

First, converting R percent to r a decimal

r = R/100 = 3%/100 = 0.03 per year,

then, solving our equation

I = 1000000 × 0.03 × 40 = 1200000

I = $ 1,200,000.00

The simple interest accumulated

on a principal of $ 1,000,000.00

at a rate of 3% per year

for 40 years is $ 1,200,000.00.
