Answer:
Step-by-step explanation:
Add and subtract the square of half the x-coefficient:
x² -10x +(-5)² -(-5)² +15
Express the first three terms as a square; simplify the remaining terms.
(x -5)² -10
This expression describes a parabola that opens upward and has its vertex at (x, y) = (5, -10). The minimum value is -10.
1) Nearest thousand: 457,000 (Look at the thousandths place. Is the number closer to 457,000 or 456,000?)
Hundred: 457,000 (Look at the hundredths place. Is the number closer to 456,000 or 457,000?)
Ten: 456,990 (Look at the tenths place. Is the number closer to 456,980 or 456,990?)
