Hi there!

Unfortunately, the set of ordered pairs does NOT represent a function! This is because there are two of the same x values. In a function, there is one input for every output. In this case, there are two of the same inputs. However, there can be two of the same outputs. 
Just to clarify - Not a function

Hope this helps!! :)

Ernie Rolph borrowed ​$3200 at 10​% annual simple interest. If exactly 1 year later he was able to repay the loan without​ penal
Setler [38]

Answer:

$320

Step-by-step explanation:

From simple interest formular

A=P(1+int) where A is amount payable, P is principal amount borrowed and int is interest gained

int=Rt where R is rate of interest in decimal form, t is duration

The rate of 10% converted to decimal is 10/100=0.1

Substituting P for $3200, R for 0.1 and t for 1 year

A=$3200(1+(0.1*1))=$3200*(1+0.1)=3200*1.1=$3520

To find the interest, it's A-P hence $3520-$3200=$320

Therefore, interest owed is $320

I need to solve for x - 6(2x-5)=-(x+4)
sdas [7]
Distribute
x-12x+30=-x-4

Combine like terms
-11x+30=-x-4

Add x to both sides
-10x+30= -4

Subtract 30 from both sides
-10x=-34

Divide both sides by -10
x=3.4

Final answer: x=3.4

1. Write the equation c = loga(b) in exponential form.
Flauer [41]

Answer:

Step-by-step explanRemember: logax=b⇒ab=x

in which "a" is the base of the log. 

log4 (1/16) = 4^-2 = 1/4^2 = 1/16

4 to the power of -2 is equal to 1/16.

To answer this question, the equation in exponential form of "log4 (1/16) = -2" is " 4^-2 " (4 to the power of -2). :D
