Answer:
The answer to your question is f(-3) = 66
Step-by-step explanation:
Data
Function f(x) = 5x² - 7x
Process
To find f(x), just substitute the -3 in all the x's of the original equation and simplify.
-Substitution
f(-3) = 5(-3)² - 7(-3)
-Simplify
f(-3) = 5(9) + 21
f(-3) = 45 + 21
-Result
f(-3) = 66
5(-3)^2-7(-3)
f(6)= 7 f(11)= 22
f(7)= 10
Step-by-step equation:
about 30,000 jeans
10,00 divided by 2 is 5,000 saying the factory can produce 5,000 jeans a month. In half a year, which is 6 months, the factory can produce 30,000 jeans . Just do 6 times 5,000
