45.3+3.21=48.51 which is greater than,its important to add the decimals because u would never know with what number your working with on decimal occasions.
Y = -2x² + 8x - 18
x = -b/2a
x = -8/2(-2)
x = -8/-4
x = 2
y = -2x² + 8x - 18
y = -2(2)² + 8(2) - 18
y = -2(4) + 16 - 18
y = -8 - 2
y = -10
(x, y) = (2, -10)
Vertex: (2, -10)
Axis of Symmetry: x = 2
Answer:
Step-by-step explanation:
r and d are the radius and diameter of a, respectively.
area of a = πr² = 500 in²
r = √500/√π = 10√5/√π
d = 20√5/√π
radius of b = 3r = 30√5/√π
area of b = π(30√5/√π)² = π(4500/π) = 4500 in²
Just rearrange the inequalities to make x the subject.
2 + y <= 3
Subtract 2 from both sides.
y <= 1
7x > 56
Divide both sides by 7.
x > 8
