The 8 rounds up so the answer is 1630
Complete the square of y^2 + 10y to answer this question.
x=y^2 + 10y + 22 becomes x = <em>y^2 + 10y + 100</em> - 100 + 22, or
x = (y+10)^2 - 78
Comparing this result to the generic form x = a(y-k)^2 + h, we see that
h = -78 and k = -10.
Then the vertex of this parabola is at (-78, -10).
Answer:
$59
Step-by-step explanation:
Half off means you pay half price. The $22 is the item of lesser value, so you pay ...
$48 + (1/2)·22 = $59
