Reflection across the x-axis:

y = − f ( x ) y = -f(x) y=−f(x) The concept behind the reflections about the x-axis is basically the same as the reflections about the y-axis.
Answer:
Step-by-step explanation:
Divide the total number of cans (5022) by the number of homerooms (18) to get the number of cans collected by each homeroom:
5022 cans
---------------------- = 279 cans per homeroom
18 homerooms
In this case there will be 2 solutions to solve for in this equation, both will equal plus and minus the answer. Which is 14.
6(3x + 5) = +_ 14
The solutions will be the following :
(14/6 - 5)/3
(-14/6 - 5)/3.
Answer:
4
Step-by-step explanation:
(6^2) -5(6) -2 =4
that is the answer
