12. Niki is going to the Pasco County Fair and she wants to go on as many rides as she can.It costs $7.50 to get into the fair a
1 answer:
The admission fee to the Fair is $7.50
The rides cost 50c each.
Let x be the number of rides she can take.
You can express her expenses in the fair as an equation:
C= total cost
C=7.50+0.5x → from this equation you can calculate how many rides she will be able to get on.
If she has a total of $23 to spend, then the number of rides can be calculated as:
With $23 she will be able to go on 31 rides.

Your answer is no solution (because a negative square root doesn't exist)
first, you divide all sides by five and then take b, half it then square it

Answer:f(x)= -8 (4x) will be the reflected function across x-axis for the function g(x).
Explanation: since we know that the image or reflection of x along x-axis = -x
That is, when we talk about a function's reflection across any axis then we have to replace variable according to that axis. For example if you have a line x=3 in positive x-axis then you can also draw a similar line x=-3 in negative x-axis. so, you can say, x=-3 is the reflection of x=3 along x axis.
Similarly, for an another line y=3, y=-3 is a reflection.
thus in the case of g(x) we can find the reflection across x-axis after replacing x by -x.
we have g(x) =8(4x)
replace x by -x we get g(-x)= 8(4×-x)= 8(-4x)=-8(4x)
so -8(4x) is the reflection of g(x)
but according to the question f(x) is the reflection of g(x) across x-axis.
Thus, f(x)=-8(4x)
