Answer:
-2x -1 if f(x) is reflected along the x axis and translated 1 unit downward
Step-by-step explanation:
A function can either be reflected along the x axis or along the y axis. If a function is reflected along the x axis, the new reflected equation g(x) is given by:
g(x) = -f(x) = -2x
g(x) = -2x
If a function is reflected along the y axis, the new reflected equation g(x) is given by:
g(x) = f(-x) = 2(-x)
g(x) = -2x
Translation means the shifting of the curve either up or down in a graph. If the reflected function is shifted 1 unit upward, the function becomes:
g(x) + 1 = -2x + 1
If the reflected function is shifted 1 unit downward, the function becomes:
g(x) - 1 = -2x - 1
1) the answer is 2, 12 - 4x = 2x, x=2.
2) x + (x+5) = 17, 2x = 12, x=6.
3) x + (3x-60) = 1220, 4x = 1280. So Fred, x, made $320. Frank made $900.
Answer:
The expression represents the total cost of the bag which contain x number of goby and x number of shrimp.
Step-by-step explanation:
Each goby fish costs $15 and each shrimp costs $10.
Each bag has an equal number of goby fish and shrimp.
So. let each bag has x number of goby and x number of shrimp
so, the cost of the bag = 15x + 10x
Take x as a common
so, the total cost = x (15+ 10)
so, the expression represents the total cost of the bag which contain x number of goby and x number of shrimp.
Answer:
x-int= (18,0), y-int= (0,-6)
