Complete the explanation of a real world situation that could be modeled
tigry1 [53]

Answer:

13, 4, and 4

Step-by-step explanation:

The absolute value of a difference measures the discrepancy between the two numbers inside.  The 13 represents the ideal amount of biscuits and x represents the actual number of biscuits in the package.  So the difference between the actual and the ideal is 4 (whether it's 4 more of 4 less than 13).

The situation described doesn't actually match the wording, because this says there'll either be 9 or 17 biscuits in the package, due to the "=".  If you wanted to have "as many as," then this should be "≤", allowing for 4 or fewer in either direction.

if Lylah completes the square for f(x)=x squared -12x+7 in order to find the minimum she must write f(x) in the general form f(x
abruzzese [7]

Answer:

A. 6

Step-by-step explanation:

f(x) = x² − 12x + 7

To complete the square, we first factor the leading coefficient to make it 1 (which it already is).

Then, we take half the second coefficient, square it, and then add to both sides.  So (-12/2)² = (-6)² = 36.

f(x) + 36 = x² − 12x + 36  + 7

Then we factor the perfect square:

f(x) + 36 = (x − 6)² + 7

Then solve for f(x) by subtracting and simplifying:

f(x) = (x − 6)² + 7 − 36

f(x) = (x − 6)² − 29

So the value of a is 6.
