Answer:
Step-by-step explanation:
The term of the sequence is given as .
To find the sixth term, which is denoted by , we substitute n=6 into the given rule.
This will give us:
Simplify the exponent to get:
We simplify further to get:
This simplifies to
Suppose that Eldi has x years old now :
x + 4 = 3 × ( x - 10 )
x + 4 = 3x - 30
Add both sides 30
x + 4 + 30 = 3x - 30 + 30
x + 34 = 3x
Subtract both sides x
x - x + 34 = 3x - x
34 = 2x
2x = 34
Divide both sides by 2
2x ÷ 2 =34 ÷ 2
x = 17
_____________________________
Thus Eldi is 17 .
$30/2=$15.
She charges $15 for one hour
Therefore, she must charge $75 for 5 hours
I think they all will make it a function.
Answer:
-(4x + 7)/2 - (3x - 2)/2 = (-4x - 7 - 3x + 2)/2 = (-7x - 5)/2
