Answer: Ravi would drive 250 miles for both plans to cost the same.
Step-by-step explanation:
Let x represent the number of miles for which Ravi needs to drive for the two plans to cost the same.
The first plan has an initial fee of $59.96 and costs an additional $0.14 per mile driven. It means that the cost of driving x miles with this plan is
0.14x + 59.96
The second plan has an initial fee of $69.96 and costs an additional $0.10 per mile driven. It means that the cost of driving x miles with this plan is
0.1x + 69.96
For both plans tho be the same, the number of miles would be
0.14x + 59.96 = 0.1x + 69.96
0.14x - 0.1x = 69.69 - 59.69
0.04x = 10
x = 10/0.04
x = 250
Lets solve f(5). First, replace all "n"s in the equation with 5s. F(5+1)=F(5)-2. This means that F(6)=F(5)-2, F(5)=F(4)-2, F(4)=F(3)-2, F(3)=F(2)-2, and F(2)=F(1)-2. Because we know F(1)=18, F(2)=16, F(3)=14, F(4)=12, and F(5)=10.

Answer:
#4
Step-by-step explanation:
The function 
represents the profit.
The 1.50 part is the price of each candy bar
The 25 part is the fixed cost incurred
This month, the price of candy bars increased by 0.25, so the "1.50" portion would be increased, NOT "25" portion [fixed cost remained same].
Thus, 1.50 would be increased by 0.25, that is:
1.50 + 0.25 = 1.75
Thus, the new profit function would be:

Answer:
y = -3x^2 -9x +30
Step-by-step explanation:
When a polynomial has a zero at x=p, it has a factor of (x -p). The factors of your quadratic are ...
f(x) = (x +5)(x -2)
At the point x=3, the value of this product is ...
f(3) = (3 +5)(3 -2) = (8)(1) = 8
In order for that value to be -24, it needs to be multiplied by a scale factor of -3. The quadratic you want is ...
y = -3(x +5)(x -2)
y = -3x^2 -9x +30 . . . . . standard form
