(9,1 ) is the solution of 64(x-8)²+ 12y² < 144 inequality.
What is solution for inequality?A solution for an inequality in x and y are numbers such that when we substitute that number for x and y we have a true statement.
We substitute x = 9 and y = 1 in each inequality. The inequality, for which the values satisfy, has (9, 1) as the solution.
1.
x² - y² > 84
81 - 1 > 84
80 > 84
not true.
2.
x >= 3(y+2)² - 2
9 >= 3(3)² - 2
9 >= 27 - 2
9 >= 25
not true.
3.
4(x-4)² - 16(y+1)² > 36
4(5)² - 16(2)² > 36
100 - 64 > 36
36 > 36
not true.
4.
64(x-8)² + 12y² < 144
64 + 12 < 144
76 < 144
True.
Hence, 64(x-8)²+ 12y² < 144 has the solution (9, 1).

Determine this one algebraically
Answer:
x = 5
y = 5
Step-by-step explanation:
In this question you need to solve one equation in order to plug the value into the second one and solve it as well. Lets start with the top one...
2x - x = 5
1x = 5
x = 5
Now we plug that value of x into the second equation
4x - 2y = 10
4(5) - 2y = 10
20 - 2y = 10
-2y = -10
y = 5
Finally, we can see that both x and y have a value of 5.
