Answer:

-3x+y should not change as it is parallel what should change is the result as you know x = 2 & y = 5 so the result is -3 × 2 + 5 = -1

A bank charges $3 each time you use an out-of-network ATM. At the beginning of the month, you have $1500 in your bank account. Y

Jlenok [28]

Answer:

$y=-\frac{63}{1} x+1500$

Step-by-step explanation:

Create a table:

1500 - 63(0) = 1500

1500 - 63(1) = 1437

1500 - 63(2) = 1374

1500 - 63(3) = 1311

Turn them into ordered pair:

(0, 1500)

(1, 1437)

(2, 1374)

(3, 1311)

A loan of $47,000 is made at 4.5% interest, compounded annually. After how many years will the amount due reach $63,000 or more?

Alex Ar [27]

$A=P(1+r)^t$ is comounded yearly formula

rat ie 4.5%
P=47000
solve for when A=63000

$63000=47000(1+0.045)^t$
divide both sides by 47000
$\frac{63}{47} =(1.045)^t$
take the ln of both sides
$ln(\frac{63}{47}) =ln((1.045)^t)$
$ln(\frac{63}{47}) =t(ln(1.045)$
divide both sides by ln(1.045)
$\frac{ln(\frac{63}{47})}{ln(1.045)}=t$
using calculator
6.656=t
so after about 6.7 years

If the monthly electrical utility bills of all customers for the Far East Power and Light Company are known to be distributed as

Y_Kistochka [10]

Answer:

A) About $195.00

Step-by-step explanation:

In a normal distribution, the interval (mean - 3*standard deviation, mean + 3*standard deviation) account for about 99.7% of the values. In this case mean + 3*standard deviation = $87.00 + 3*$36.00 = $195.00. So, it 's expected that this amount of money would be the largest individual customer bill.
