Step-by-step explanation: In order for a function not to be a relation,

each x-coordinate must correspond to more than one y-coordinate.

Notice that in third relation, the 1 pairs with a 3

in one case and it pairs with a 7 in the other case.

Since each x-coordinate pairs with more than one y-coordinate,

this relation is not a function but the other ones are functions.

Answer:

<h3>Question 1 </h3>

<em>Adjacent angles are supplementary, opposite angles are equal</em>

62 + 5x + 3 = 180
5x = 180 - 65
5x = 115
x = 23

62 = 3y + 2
3y = 60
y = 20

<h3>Question 2</h3>

<em>Diagonals bisect each other</em>

4x = 3x + 7
x = 7

6y = 2y + 16
4y = 16
y = 4

Correct choice is A

At the beginning of year 1, Josie invests $400 at an annual compound interest

zvonat [6]

Answer:

The explicit formula that can be used is $A=\$400(1.05)^{2}$

The account's balance at the beginning of year 3 is $A=\$441$

Step-by-step explanation:

we know that

The compound interest formula is equal to

$A=P(1+\frac{r}{n})^{nt}$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

in this problem we have

$t=2\ years\\ P=\$400\\ r=0.05\\n=1$

substitute in the formula above

$A=\$400(1+\frac{0.05}{1})^{1*2}$

$A=\$400(1.05)^{2}$

$A=\$441$
