To see if (2,5) is a solution of the line y = 3x - 10, you need to plug in the coordinate values for x and y. This gets you 5 = 3(2) - 10. Evaluating the right side gives 5 ≠ -4, which is not a true statement. This means that the answer to your problem is no, (2,5) is not a solution of y = 3x - 10. Hope this helps and have a nice day!

Answer:
16
Step-by-step explanation:
4 flavors
2 toppings
2 containers
4x 2= 8
8x2=16
(x - 2)² + 1 = 0
(x - 2)(x - 2) + 1 = 0
x(x - 2) - 2(x - 2) + 1 = 0
x(x) - x(2) - 2(x) + 2(2) + 1 = 0
x² - 2x - 2x + 4 + 1 = 0
x² - 4x + 4 + 1 = 0
x² - 4x + 5 = 0
x = <u>-(-4) ± √((-4)² - 4(1)(5))</u>
2(1)
x = <u>4 ± √(16 - 20)</u>
2
x = <u>4 ± √(-4)
</u> 2<u>
</u> x = <u>4 ± 2i</u><u>
</u> 2<u>
</u> x = 2 ± i
x = 2 + i U x = 2 - i
The solution set is {2 ± i}.
