The diagram that best represents X' is letter C.

Explanation:

X' represents anything but X.

Because of this, the union of X and Y is not shaded in, as well as the X circle. Anything that doesn't include X should be shaded in green.

Y * x = 20<br><br> y + x = 9 <br><br> what numbers are y and x equal to?
Ksivusya [100]

y = 9 - x
Substitute into
y \times x = 20 \\ (9 - x) \times x = 20 \\  { - x}^{2}  + 9x = 20 \\  {x}^{2}  - 9x  + 20 = 0 \\ (x - 5)(x -4) = 0 \\  x = 5 \: or \: x = 4
When x = 5,
y = 9 - 5 \\ y = 4
When x = 4,
y = 9 - 4 \\ y = 5

x = 5, y = 4
x = 4, y = 5

Hope this helps. - M

Which expression is equivalent to 4x2 - 4x – 3 in factored form?
erastovalidia [21]

Answer:

(2x-3)(2x+1)

Step-by-step explanation:

4x^2 - 4x - 3

we need two numbers that give 12 when multiplied and 4 when subtracted

the numbers are 6 and 2 because 6*2=12 and 6-4=4.

4x^2 - (6-2)x -3

4x^2 -6x +2x -3

take common

2x(2x -3)+1(2x-3)

take (2x-3) as common

(2x-3)(2x*1 + 1*1)

(2x-3)(2x+1)
