It is the second function:
y=(1/2)^(x-3)
When x=0, the exponent is -3. (1/2)^-3 is 8.
y = 8+1 = 9
Let us take the case of 7 pounds for $8.47 first.
7 pounds of a product costs = 8.47 dollars
Then
1 pound of the same product will cost = (8.47/7) dollars
= 1.21 dollars
Now let us take the case of 9 pounds for $11.07
9 pounds of a product costs = 11.07 dollars
Then
1 pound of the same product will cost = (11.07/9) pounds
= 1.23 dollars
So from the above deductions we can see that 9 pounds for $11.07 is a better buy than 7 pounds for $8.47. I hope the procedure is clear enough for you to understand. In future you can use this method for solving similar problems.
the answer is 95.
Step-by-step explanation:
180-85=95
300 = 2(x + x + 10)
300 = 2(2x +10)
300 = 4x + 20
4x = 280
x = 70
x + 10 = 80
width = 80ft

Answer:
8
Step-by-step explanation:
The x intercept is when y = 0
x + 3(0) = 6
x = 6
So (6,0) and m = 6
the y intercept is when x = 0
0 + 3y = 6 Divide by 3
y = 6/3
y = 2
the y intercept is (0,2) and n = 2
Answer
m + n = 6 + 2 = 8
