A1. 12 i.e option D
A2. 3n-7 i.e option A
A3. -6n+20 i.e option D
A4. -70 i.e option C
Step-by-step explanation:
aₙ = a₁ + (n - 1) × d
aₙ = the nᵗʰ term in the sequence
a₁ = the first term in the sequence
d = the common difference between terms
Using the above formula to solve the first part, we have :
For the second part, we have :
For the third part, we have :
For the fourth part, we have :
The sum of the individual lunch ate by people is equal to the total number of people who ate lunch.
<h3>What is an
equation?</h3>
An equationi is an expression that shows the relationship between two or more variables and number.
Given that the total number of people who ate lunch is 840, hence:
The sum of the individual lunch ate by people is equal to the total number of people who ate lunch.

I think the answer is negative 8 square root 726
then the answer if I am right sorry if I am not would be negative 88 square root 6
again sorry if wrong
Answer:

Step-by-step explanation:
To find inverse of a function, follow the steps below:
1. replace h(x) with y
2. Interchange x and y
3. Solve for the new y
4. Replace y to
(this is the inverse function)
<u>Step 1:</u> y = -2/3x+6
<u>Step 2:</u> x = -2/3y+6
<u>Step 3:</u>

<u>Step 4:</u>

This is the inverse function.
