The value of x from the given parameters is x = -1/7

<h3>How to determine the value of x?</h3>

The given parameters are:

Point E is between points D and F

DF = 18x - 1

DE = 3x + 5

EF = -x - 8

The statement point E is between points D and F, means that

DF = DE + EF

Substitute the known values in the above equation

So, we have:

18x - 1 = 3x + 5 + x - 8

Collect the like terms

So, we have

18x - 3x - x = 5 - 8 + 1

Evaluate the like terms

14x = -2

Divide both sides by 14

x = -1/7

Hence, the value of x from the given parameters is x = -1/7

False, this statement is not true, because if you change the parenthesis, it means that you will do that thing first (PEMDAS)
Therefore, the sstatement is false, because the answers will be completely different,

Answer:

$t \leq 18.67\ years$

Step-by-step explanation:

we know that

The simple interest formula is equal to

$A=P(1+rt)$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest

t is Number of Time Periods

in this problem we have

$t=?\ years\\ P=\$4,500\\ A=\$7,020\\r=0.03$

The inequality that represented this situation is

$P(1+rt) \leq A$

substitute the values and solve for t

$4,500(1+0.03t) \leq 7,020$

$(0.03t) \leq (7,020/4,500)-1$

$t \leq [(7,020/4,500)-1]/0.03$

$t \leq 18.67\ years$
