Umm maybe try:
f^-1 (x) = -4x/3 + 32/3
let me know if that’s right
Answer:
∴ ∑₁⁸i = 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8
Step-by-step explanation:
Given:
To Find:
∑₁⁸i =?
Solution:
Σ This symbol called Sigma means "summation up"
∴ ∑ n mean sum for all n
But if ∑₁³n means Sum for n=1 , 2 ,and 3 ADD
∴ ∑₁³n = 1 + 2 + 3
∴ ∑₁⁸i = 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8

Answer:
This means jorge must work for at least 36 hours to earn $1,000. The inequality that represent this expression is h
36
Step-by-step explanation:
Given the amount of money jorge earns for (h) hours of work expressed as 100 + 25 (h). If jorge must work to earn at least $1,000, this means that the lowest amount jorge can earn is $1,000. Jorge cannot earn below but above $1000 i.e he will always earn amount greater than or equal to $1,000.
The statement can be represented using the inequality;
100+25h
1000
To know the number of hours jorge must work to earn at least $1000, we can solve the inequality function for 'h'
Subtarcting 100 from both sides;
100+25h-100
1000-100
25h
900
dividing both sides by 25

This means jorge must work for at least 36 hours to earn $1,000
(2x-1)(4x+1) just multiply the terms in the parentesis
Do the following:
2x*4x
2x*1
-1*4x
-1*1
You get:
8x^2+2x-4x-1
Final result:
8x^2-2x-1
