Answer:
In an equation y = a(x - h) + k, the axis of symmetry will be x = h. This is because (h, k) is the vertex, and the parabola will be symmetric on both sides of the vertex.
X² + y² - 4 x + 2 y = b
x² - 4 x + 4 + y² + 2 y + 1 = b + 4 + 1
( x - 2 )² + ( y + 1 )² = b + 5
y - coordinate of the center of the circle is: y = - 1
b + 5 = r
b + 5 = 7
b = 7 - 5
b = 2
Answer:
Bonnie is correct.
Step-by-step explanation:
Input 5 for the amount of shirts for letter X then follow the steps for a multistep equation:
12(5) - 10 = 50
60 - 10 = 50
50 = 50
x = x or 1
So, Susan, as Bonnie said, can buy 5 shirts.
So if the package costs $4, and there are 8 pens, how much does each pen cost?
