First Question
Option A is correct
Second Question
Option C is correct
Third Question

Fourth Question
So substituting for D in (ABC) D = I


This proof that ABC is invertible
Step-by-step explanation:
From the question we are told that
A , B and C are invertible which means that
exist
Now
From the question
(ABC) D = I
Where I is an identity matrix
Now when we multiply both sides by
we have


Now when we multiply both sides by
we have


Now when we multiply both sides by
we have



So substituting for D in the above equation


This proof that ABC is invertible

Answer:
A. $2,000
Step-by-step explanation:
<em>Assuming that the money in the savings account will be used to pay off for tractor.</em>
<em>let the number of months be m</em>
Savings after m months will be 500+ 150m
After m months the installments paid will 200m
To find the months it will take to pay for the tractor in m months, savings and the installments will be the price of the tractor. As an equation it be represented as below:
500+150m +200m = 4000
150m + 200m = 4000-500 <em>(grouping like terms)</em>
350m = 3500 <em>(Making m the subject of the formula)</em>
350m/350 = 3500/350
m = 10
Substituting m into the equation of saving after m months
<em>Savings after m months will be</em> 500+ 150m
<em>Savings after m months will be</em> 500 + 150(10)
<em>Savings after m months will be</em> 500 + 1500
Savings after m months will be $2000
