I think the answer is (7x-3)(7x+3)
Answer:
The first option is the correct option
Step-by-step explanation:
From the question the slope AC is evaluated as
And the slope of line CB is mathematically evaluated as
Now for lines that are perpendicular to each other then the product of their slope should be equal to -1
So if
Then
i,e
Answer:
Remaining tickets left to distribute, A = (300 - 10m)
Step-by-step explanation:
a) Let the number of choir members be m
Let the number of tickets remaining after the distribution be A
Each choir member is to get 10 tickets each.
Number of tickets to be given to the members = 10m
original number of tickets = 300
So, number of tickets remaining after distribution, A = 300 - 10m (provided that m ≤ 30)
b) The independent variable in this expression is m (the number of choir members)
And the dependent variable is A (the number of tickets left after the distribution which depends on the number of choir members, m)
Hope this Helps!!!
