The option A and B would be wrong since it was less than the minimum value of the function. To find the cost, you just need to replace the x variable with time after 2005.
If the time is 2025 it will be
x= 2025-2005= 20
y = 15.7x + 459
y = 15.7(20) + 459
y = 314+ 459 = <span>$773.00
</span>
If the time is 2030 it will be
x= 2030-2005= 25
<span>y = 15.7x + 459
</span><span>y = 15.7(25) + 459
</span>y = 392.5+ 459 =<span>$851.50</span><span>
</span>
What I’m support to fine it in the graph or find the slop, solve for x or y???? Put the whole question so I can help you
A variable Because of the math question like let’s say 40•12*-* divided by x
The greatest common factor of

and

is
gcd(m*m*n*n, m*n*n*n) =m*n*n=

what we did, was to see how many m's and how many n's, each expression have, and then pick the smallest of each letter (factor).
the reason is that the common factor, must have enough m's and n's to divide the m's and n's of both expressions
so

also

thus, n is equal to 3
Answer: A)3
Multiply -8 by -4, then add fifteen! Your answer will be 47!
