Which of the or the following ordered pairs is a solution of x+1/2 y=1?
2 answers:
The answer is (-2,6). -2 will replace x variable and 6 will replace the y variable. when it is plug in you may simplify.
x + 1/2 y =1 .... -2 + 1/2 * 6 = 1 .... (half of 6 is 3) ..... -2 + 3 = 1 .... 1 = 1
Answer:
Option a) (-2,6)
Step-by-step explanation:
We are given the following information in the question:
![x+\displaystyle\frac{1}{2}y=1](https://tex.z-dn.net/?f=x%2B%5Cdisplaystyle%5Cfrac%7B1%7D%7B2%7Dy%3D1)
a)(-2,6)
![(-2)+\displaystyle\frac{1}{2}(6)=-2 + 3 = 1](https://tex.z-dn.net/?f=%28-2%29%2B%5Cdisplaystyle%5Cfrac%7B1%7D%7B2%7D%286%29%3D-2%20%2B%203%20%3D%201)
Thus, it is a solution of the given equation.
b)(2,-6)
![(2)+\displaystyle\frac{1}{2}(-6)=2 - 3 = -1](https://tex.z-dn.net/?f=%282%29%2B%5Cdisplaystyle%5Cfrac%7B1%7D%7B2%7D%28-6%29%3D2%20-%203%20%3D%20-1)
Thus, it is not a solution of the given equation.
c)(-2,-6)
![(-2)+\displaystyle\frac{1}{2}(-6)=-2 - 3 = -5](https://tex.z-dn.net/?f=%28-2%29%2B%5Cdisplaystyle%5Cfrac%7B1%7D%7B2%7D%28-6%29%3D-2%20-%203%20%3D%20-5)
Thus, it is not a solution of the given equation.

Answer
33,33 and 22
Step-by-step explanation:
The inequality is:
![x\geq15](https://tex.z-dn.net/?f=x%5Cgeq15)
4(-3 + -2d) = 12
(-3 * 4 + -2d * 4) = 12
(-12 + -8d) = 12
-12 + -8d = 12
-12 + 12 + -8d = 12 + 12
-12 + 12 = 0
0 + -8d = 12 + 12
-8d = 12 + 12
12 + 12 = 24
-8d = 24
d = -3
