Answer:
g(2)=1
Step-by-step explanation:
We need to use the second definition of the function since x=2
g(2) = 2^3 -9(2)^2 +27(2) -25
= 8-9(4) +54 -25
= 8-36+54-25
= 1
Let's make a system of equations.
1 large bottle = l
1 regular bottle = r
l + r = 113
221 = 2.5l + r
Isolate r in the first equation and substitute it into the second equation:
l + r = 113
r = 113 - l
---
221 = 2.5l + 113 - l
221 = 1.5l + 113
108 = 1.5l
72 = l
Now, substitute that back into the first equation:
l + r = 113
72 + r = 113
r = 41
Finally, check your work by substituting back into both equations:
72 + 41 = 113 --> 113 = 113 <-- True
221 = 2.5(72) + 41 --> 221 = 180 + 41 <--True
Answer:
Franklin sold 72 large bottle of water and 41 regular-sized bottles of water.
Answer:
No answer
Step-by-step explanation:
You seemed to have not pisted the whole question. if you need to find the cost of a certain number of cones, use this equation.
Y=2.49x
Let Y equal the total cost
Let x equal the number of cones
I hope this helps you
f(8)=2.8+5=21
g(8)=3.8+6=30
f-g(8)=21-30= -9
Resolving a function of any nature means determining your zeros or raizes.
The zeros of a function occur when the function is null.
Then:
f(x) = 3x - 2
To determine the root
f(x) = 0 = 3x - 2
3x = 2
x = 2/3 Final result
