Answer: See attached

Step-by-step explanation:

[] Since the inequality uses greater than (>) and not greater than or equal to (≥), the line will be dashed.

[] The inequality is greater than (>) so we will shade above the line as values "above" are greater.

Does it lie inside, outside, or on the circle?

FrozenT [24]

Answer:

Given circle:

(x - 4)² + y² = 25

The center is at (4, 0) and the radius is 5 units

Lets find the distance from (7, 2) to the center of the circle:

$d = \sqrt{(7 - 4)^2 + (2 - 0)^2} = \sqrt{9+4} = \sqrt{13} < 5$

Since d < 5, the point (7, 2) lies inside the circle

Fill in the blank space z2 + 5z – 36 = (z – 4)(z +_)

labwork [276]

Answer=9

To solve this, we just have to find a number that, when added to -4, make a total of 5, and when multiplied by -4 make a total of -36.

x+-4=5

x*-4=-36

9 fits the parameters for both of these

9+-4=9
9-4=5
5=5

9*-4=36
36=36

Answer:

$\dfrac{3x+4}{2x-2}$

Step-by-step explanation:

Invert and multiply the way you would any fraction division problem. Then cancel common factors from numerator and denominator.

$\displaystyle\frac{\left(\frac{4x^2+2x}{x^2+x-2}\right)}{\left(\frac{8x^2+4x}{3x^2+10x+8}\right)}=\frac{4x^2+2x}{x^2+x-2}\cdot\frac{3x^2+10x+8}{8x^2+4x}\\\\=\frac{2x(2x+1)(3x+4)(x+2)}{4x(2x+1)(x-1)(x+2)}=\frac{3x+4}{2(x-1)}\\\\=\frac{3x+4}{2x-2}$

The function g(n) = n2 − 16n + 69 represents a parabola.

miss Akunina [59]

Hello :
g(n) = n2 − 16n + 69
=( n²-16n+64)-64 +69.....( completing the square)
g(n) = (n-8)² +5...... (the vertex form)
the vertex is : (8,5)
the axis of symmetry is the line : n = 1
