Let x equal the number of books bought.
45 = 3x - 6
(This is the answer because $45 is the total price, each book is $3, and $6 is discounted from the actual price.)
Answer:
20 sec
Step-by-step explanation:
the average adult male can run 100 m in 18 seconds, you could reasonably assume 20 seconds is a fair answer
Answer:
The polynomial would be f(x) = x^3 + 4x^2 - 5x
Step-by-step explanation:
In order to find this, start with the equations that x is equal to each of the solutions. Then solve each of those expressions for 0.
-5 = x
0 = x + 5
1 = x
0 = x - 1
0 = x
Now put each of the terms that you have in parenthesis and multiply them all together.
f(x) = (x)(x + 5)(x - 1)
f(x) = (x)(x^2 + 4x - 5)
f(x) = x^3 + 4x^2 - 5x
Answer:
24
Step-by-step explanation:
18=75%
so
6=25%
18+6=24
