2t<-4 divide both sides by 2
t<-2
...
7t>49 divide both sides by 7
t>7
So t=(-oo,-2) and t=(7,+oo)
t=(-oo,-2)U(7,+oo)
Answer: 1/2 is correct.
Step-by-step explanation:
There are 8 total parts, and 4 of them are shaded. 4 is half of 8, therefore, your answer is 1/2.
Hope this helps!
If 12 students make up 24% of the population, 1 student is 2% of the population because 24/12=2
100/2%=50
I did this because the population would be 2% times # of students= 100%
divide 100 by 50 to get 2 percent or 100/ 2 percent to get 50 students

<h3>Explanation:</h3>
Matrices can only be added if they are the same dimensions. Choices B and D have different dimensions than a 2×1 matrix representing a point. Choice C would translate the point to a position 1 unit up and 1 unit to the right of its original location.
![\left[\begin{array}{c}x\\y\end{array}\right] +\left[\begin{array}{c}0\\0\end{array}\right] =\left[\begin{array}{c}x\\y\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7Dx%5C%5Cy%5Cend%7Barray%7D%5Cright%5D%20%2B%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7D0%5C%5C0%5Cend%7Barray%7D%5Cright%5D%20%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7Dx%5C%5Cy%5Cend%7Barray%7D%5Cright%5D)
