Separate the 1st 2 terms from the 3rd term:
y = x^2 - 8x + 7
Next, take half of the coefficient of x (that is, half of -8).
In this case that'd come out to -4.
Square this -4 and add the result (16) to x^2 - 8x: x^2 - 8x + 16; subtract -16 from 7:
x^2 - 8x + 16 7 - 16
Write the trinomial as
a perfect square:
(x-4)^2 -9
The answer is (x-4)^2 - 9.
This approach is very useful. Note that the vertex of the parabola represented by the given polynomiql is (4,-9).
Answer:
$25.75 times .2 (20% of a whole 1 or in this case 100%) gives $5.15
so 25.75-5.15=<u>$20.60</u>
Step-by-step explanation:
Answer:
25x
Step-by-step explanation:
25•x is 25x.
Until you know what x is you cannot do anything
Once you find out what x is you can plug in the number in the x space to get 25•__
I hope this helped!
