Answer:
The function f(x) is not given, I used a different function but the approach and steps is the same .
Step-by-step explanation:
- Given the function f(x) = 2x2 - 8x + 5
compare with the normal quadratic equation ; ax2 + bx + c = f(x)
- since a is greater than zero i.e a > o {positive}
As such, it has a minimum
hence for minimum value; x = -b/2a
x = -(-8)/2 x 2
x = 8/4 = 2
plugging the values of x in f(x) ; f(2) = 2(2)^2 -8(2) + 5
f(2) = -3, hence it has minimum value and the minimum value is -3
Answer:
$62.42
Step-by-step explanation:
1st step: Simplify the numbers first
$24.99 -------> 25
$12.99 ---------> 13
$4.49 ----------> 4
$19.95 ---------> 20
25+13+4+20= 62
cents from simplified version: 42 cents are added to the final number
$0.42+ $62.00 = $62.42
Total Cost: The four athletic items will cost $62.42 in total.
Hope this helps!!!

Answer:
c/8 =__
Step-by-step explanation:
Let x= number of board games
<span>20x=10410+2.65x </span>
<span>-2.65 -2.65 </span>
<span>17.35x=10410 </span>
<span>/17.35 /17.35 </span>
<span>x=600 </span>
<span>You would need to sell at least 600 board games to break even</span>
