Answer: 2.7725
Step-by-step explanation:
Answer:
3
Step-by-step explanation:
The question gives you the x coordinate, so plug in x with 3.
y=4(3)-9
y=12-9=3
y=3
(3,3)
Answer:
-9A · √(5yA)
Step-by-step explanation:
The coefficient -3 stays the same.
45 factors into 5·9, which is helpful because 9 is a perfect square.
Thus, √45 = 3√5.
y cannot be factored. It stays under the radical.
A³ can be factored into A² (a perfect square) and A.
Thus,
-3√(45yA³) = -3 · 3√5 · √y · A · √A, or
= (-3)(3)(A) · √(5yA), or
= -9A · √(5yA)
Xy = 450
y = x/2 => x=2y substituted inside first equation will get 2y*y=450 => y^2 = 225
y=15 because 15*15=225
x=2y so x=2*15 = 30
x=30
y=15
