g > 6.4

<h3>Answer: A. 7 > 6.4</h3>

y + 2 > 8 <em>subtract 2 from both sides</em>

y > 6

<h3>Answer: D. 7 > 6</h3>

6 > z(10 - z)

A. z = 0 → 6 > 0(10 - 0) → 6 > 0 CORRECT

B. z = 1 → 6 > 1(10 - 1) → 6 > 1(9) → 6 > 9 FALSE

C. z = 2 → 6 > 2(10 - 2) → 6 > 2(8) → 6 > 16 FALSE

D. z = 3 → 6 > 3(10 - 3) → 6 > 3(7) → 6 > 21 FALSE

<h3>Answer: A. 0</h3>

The list of factors of 24:

1, 24, 2, 12, 3, 8, 4, 6

<h3>Answer: D. {1, 2, 3, 4, 6, 8, 12, 24}</h3>

1) Answer: $\frac{x^{2}}{100} +\frac{y^{2}}{4} = 1$

<u>Explanation:</u>

The equation of an ellipse is: $\frac{(x-h)^{2}}{a^{2}} +\frac{(y-k)^{2}}{b^{2}} = 1$ ; where (h, k) is the center, "a" is the x-radius, and "b" is the y-radius.

Center Radius

x-axis: (10 + -10)/2 = 0 10 - 0 = 10

h = 0 a = 10

y-axis: (2 + -2)/2 = 0 2 - 0 = 2

k = 0 b = 2

Now, input the values into the equation:

$\frac{(x-0)^{2}}{10^{2}} +\frac{(y-0)^{2}}{2^{2}} = 1$

$\frac{x^{2}}{100} +\frac{y^{2}}{4} = 1$

2) Answer: $\frac{x^{2}}{1} +\frac{(y+2)^{2}}{4} = 1$

<u>Explanation:</u>

Vertices are: (0, 1) and (0, -5) ------> x-values are the same, y = 1, -5

Covertices are: (-1, -2) and (1, -2) ----> y-values are the same, x = -1, 1

Center Radius

x-axis: (-1 + 1)/2 = 0 1 - 0 = 1

h = 0 a = 1

y-axis: (1 + -5)/2 = -2 1 - (-2) = 3

k = -2 b = 3

Now, input the values into the equation:

$\frac{(x-h)^{2}}{a^{2}} +\frac{(y-k)^{2}}{b^{2}} = 1$

$\frac{(x-0)^{2}}{1^{2}} +\frac{(y-(-2))^{2}}{3^{2}} = 1$

$\frac{x^{2}}{1} +\frac{(y+2)^{2}}{9} = 1$
