H (x) = 5x^2+40x+64
y = (5x^2+40x+60) + 4
y = 5(x^2+8x+12) + 4
y = 5(x+2)(x+6) + 4
y-4 = 5(x+2)(x+6)
This means that the solutions, or where the parabola crosses the x-axis, are at x+2=0 and x+6=0, or x=-2, -6
So the midpoint of -2 and -6 is -4, the axis of symmetry is x=-4
Step-by-step explanation:
First convert the amount of dough into an improper fraction:
Each roll is 1/8 lb so divide the amount of dough by this amount:
Into an improper fraction. An improper fraction is a fraction where the denominator is smaller than the numerator.
Example: Mixed number: 1 2/3
Improper fraction: 5/3
Answer:
Step-by-step explanation:
x²- y² = (x+y) (x-y)
x² + xy = x(x+y)
x² + 2xy + y² = (x+y) (x+y)
Answer:
in -5y+8x=-18 and 5y+2x=58
x = 4
in -5y+8x=-18 and 5y+2x=58
y = 10
