Answer:
y = -9x + 4
The equation for slope is y=mx + b
288
9 times 2 is 18 18 times 2 is 36 keep multiplying
53361 + 9.5b = 25.25b
53361 = 25.25b - 9.5b
53361 = 15.75b
53361/15.75 = b
3388 = b <=== the publisher would have to sell 3388 books
Hello!
You need to find what makes it equal 6
3n - (2 + n) = 6
You can distribute the -1
3n - 2 - n = 6
Combine like terms
2n - 2 = 6
Add 2 to both sides
2n = 8
Divide both sides by 2
n = 4
The answer is 4
Hope this helps!
