Answer:
Step-by-step explanation:
X^4 - 10X^2 + 9 =0 This factors. It just looks odd.
(x^2 - 1)(x^2 - 9) = 0
x^2 - 1 = (x + 1)(x - 1) = 0
x = 1 and x = - 1
x^2 - 9 = (x + 3)(x - 3) = 0
x = 3
x = -3
The correct answer is C (third one down).
Pretty sure it is altitude sorry if im wrong
The ratio is 1/1.5 so just pick the answers where the first number multiplied by 1.5 is equal to the second number.
For example the first option says 2 and 3.
2 times 1.5 is equal 3 so that is one of the answers.
If an option says 4 and 5, 4 times 1.5 is 6 not 5 so that wouldn't be an answer.
Answer:
[-17, -![\frac{9}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B4%7D)
graph would be closed circle, shaded to the left and the point placed a little over -2 bc -9/4 THEN another closed circle on -17 shaded to the right so they meet in the middle
Step-by-step explanation:
-x-5 greater than or equal to 3x+4
-x-5 ≤ 12
x ≤ -9/4
-z-5 ≤ 12 ===== x > -17 (make sure to put a line under the >)
Answer:
0.5625 since 4.5 / 8 is that value
