Answer:
f(2)=-15
Step-by-step explanation:
y+4x^2-1 is the same as y=-4x^2+1, then replace y with f(x); f(x)=-4x^2+1. After you do that, replace x with 2; f(2)=-4(2)^2+1. 2^2=4, 4 times -4=-16, -16+1=-15. So f(2)=-15.
The answer is B
Explanation: you start with 177.25 the total and subtract 7.5. Then you grab 169.75 and divide by 5. Getting you 33.95

Step-by-step explanation:
can you be a bit more specifoc on BLaNk?
Step-by-step explanation:
a)
t(x) = x*(1 + 0.06)
b)
d(x) = x*(1 + 0.06)*(1 - 0.1)
c)
It doesn't matter because a * b = b * a
So x*(1 + 0.06)*(1 - 0.1) will be the same as xx*(1 + 0.06)*(1 - 0.1)*(1 + 0.06).
1.9 because if the number after it is lower then it is just the first number
