Start by distributing -5x into x then into -3y. So -5x times x equals -5x^2( -5x squared), then -5 times -3y, equals 15xy so your answer is -5x^2 + 15xy.
Disjunction would be statements connected with <span>or.

Answer:
Yes it is linear
Step-by-step explanation:
Because when you go to graph it, it is a straight line. Hope this helped.....
Answer:
C
Step-by-step explanation:
Absolute Value is the distance from 0, so when you have -|22| that means its the absolute value of 22 then add the negative sign so that means it's further from 0 than |-22|.
I hope this will help.
<u>Answer:</u>
x = 0.417 or x = -0.917
<u>Step-by-step explanation:</u>
We are given the following expression and we are to solve it for the variable x:
![x ^2 + \frac { 1 } { 2 } x + \frac { 1 } { 1 6 } = \frac { 4 } { 9 }](https://tex.z-dn.net/?f=%20x%20%5E2%20%2B%20%5Cfrac%20%7B%201%20%7D%20%7B%202%20%7D%20x%20%2B%20%5Cfrac%20%7B%201%20%7D%20%7B%201%206%20%7D%20%3D%20%5Cfrac%20%7B%204%20%7D%20%7B%209%20%7D%20)
We will find the least common multiple of 2. 6 and 9:
![x^2 \times 144 +\frac{1}{2}x \times 144 +\frac{1}{16} \times 144 = \frac{4}{9} \times 144](https://tex.z-dn.net/?f=x%5E2%20%5Ctimes%20144%20%2B%5Cfrac%7B1%7D%7B2%7Dx%20%5Ctimes%20144%20%2B%5Cfrac%7B1%7D%7B16%7D%20%5Ctimes%20144%20%3D%20%5Cfrac%7B4%7D%7B9%7D%20%5Ctimes%20144)
Simplifying it to get:
![144x^2+72x+9=64](https://tex.z-dn.net/?f=144x%5E2%2B72x%2B9%3D64)
![144x^2+72x+9-64=0](https://tex.z-dn.net/?f=144x%5E2%2B72x%2B9-64%3D0)
![144x^2+72x-55=0](https://tex.z-dn.net/?f=144x%5E2%2B72x-55%3D0)
Using the quadratic formula to solve for x:
![x=\frac{-b \pm\sqrt{b^2-4ac} }{2a}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-b%20%5Cpm%5Csqrt%7Bb%5E2-4ac%7D%20%7D%7B2a%7D)
![x=\frac{-72 \pm\sqrt{72^2-4(144)(-55)} }{2a}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-72%20%5Cpm%5Csqrt%7B72%5E2-4%28144%29%28-55%29%7D%20%7D%7B2a%7D)
or ![0.417](https://tex.z-dn.net/?f=0.417)
or ![-0.917](https://tex.z-dn.net/?f=-0.917)
