Answer:
Step-by-step explanation:
) Nth term = F + (N - 1) x D, where F=First term, N=Number of terms, D=Common difference
6th row = 23 + (6 - 1) x -3
= 23 + (5) x -3
= 23 + (-15)
= 8 - number of boxes in the top row.
b) Sum = N/2[2F + (N - 1) x D]
= 6/2[2*23 + (6 - 1) x -3]
= 3 [46 + (5) x -3 ]
= 3 [46 + -15 ]
= 3 [ 31 ]
= 93 - total number of boxes in the entire display.
The inverse of the given function is y = (12-x)/6
<h3>Inverse of a function</h3>
Given the following function expressed as:
f(x) = -6x +1/2
Replace y with x
x = -6y + 1/2
Make y the subject of the formula
6y = -x + 12
y = (12-x)/6
Hence the inverse of the given function is y = (12-x)/6
