Answer:

The answer is B.

Step-by-step explanation:

A function is a set of ordered pairs in which each x-element has only ONE y-element associated with it. While a function may NOT have two y-values assigned to the same x-value, it may have two x-values assigned to the same y-value. Function: each x-value has only ONE y-value!

Hope this helps :)

At age 23​, someone sets up an IRA​ (individual retirement​ account) with an APR of ​7%. At the end of each month he deposits ​$
MAVERICK [17]

Answer:

The ira will contain $228,278.05 when he retires at age 65. This is 6.04 times the amount of money he deposited.

Step-by-step explanation:

In order to solve this problem, we can make use of the following formula:

FV=PMT[\frac{(1+i)^{n}-1}{i}]

Where:

FV= Future value of the ira

PMT= the amount of money you deposit each month

i= is the interest rate per period

n=number of periods

in this case we will assume the interest will be compounded each month.

So:

FV this is what we need to know.

PMT= $75  the amount he will deposit each month

t = 42 years,

this is 65-23=42

n=42 years * 12 months/year = 504 months

i=0.07/12

So we can now use the given formula:

FV=PMT[\frac{(1+i)^{n}-1}{i}]

FV=75[\frac{(1+\frac{0.07}{12})^{504}-1}{\frac{0.07}{12}}]

So we get:

FV=$228,278.05

which is the amount of money he will have after 42 years.

In total, he deposited:

$75*504months = $37,800

so he will have:

\frac{228,278.05}{37,800}=6.04 times the amount of money he deposited throughout this time.

PLEASE HELP I DONT UNDERSTAND!!
qaws [65]

First set both equations equal to y

y = -1/2x + 3

y = 3x - 4

Then set these two equal because they both equal y

-1/2x + 3 =  3x + 4

Combine like terms and solve

7 = 3.5x

x = 2

y also = 2 when you plug it back in

Therefore, (2,2)
