Y=-4x²+4x-1 this quadratic equation is of the form ax² + bx + c
and its discriminante is ( Δ = b²- 4ac)
:
So Δ = b² 4ac ==> (4)² - 4(-4)(-1)==> (16) -16 = 0
When Δ = 0, the parabola intercept x=axis in one & only one point
And the x-intercept = -b/2a = (-4)/[2.(-4)] ==> x = 1/2
Answer:
The definition of biased is unfairly showing favoritism towards something or someone. If you favored one of the candidates going into a contest over the other, this is an example of when you were biased. adjective.

I just learned this not that long ago lol
Answer:
Answer is A
Step-by-step explanation:
a+a+a+a+b+b =4a+2b
If |2w - 3| > 5
then
2w - 3 < - 5 or 2w - 3 > 5
2w < - 5 + 3 or 2w > 5 + 3
2w < - 2 or 2w > 8
w < -2/2 or w > 8/2
w < -1 or w > 4
So the solution set is
S = { x E R : w < -1 or w > 4}
or using the interval notation
S = (- infinity, -1) U (4, + infinity).
I hope this helps. =)
Answer:
<h2><em><u>
a) is correct</u></em></h2>
3n + 5
1. Substitute the numbers
3(5) + 5 = 15 + 5 = <em><u>20</u></em>
2. Substitute the second number
3(6) + 5 = 18 + 5 = <em><u>23</u></em>
<h2><u><em>
b) Numbers are 8 and 16.</em></u></h2>
This is because I realized I got the number of 4 last because I did 1*2 = 2.
Then I did 2*2 = 4.
So you have to multiply by two to get the next number. Or you can put it to the 4th or 5th exponent of 2.
1. 1
2. 1*2 = 2
3. 2*2 = 4
<h2><em><u>
4. 4*2 = 8</u></em></h2><h2><em><u>
5. 8*2 = 16</u></em></h2>
