Answer:
The answer is C :)
Step-by-step explanation:
The value of y from the given expression is 5
<h3>
Perpendicular Bisector</h3>
Given:
BD = 16
BC = 2y - 2
CD = y + 3
Since AC is a perpendicular bisector of BD:
BC = CD
2y - 2 = y + 3
2y - y = 3 + 2
y = 5
Hence, the value of y from the given expression is 5

Standard form : Ax + By = C
y = 2x + 5....subtract 2x from both sides
-2x + y = 5...multiply by -1 to make x positive
2x - y = -5 <=== standard form
Answer:
A. Approximately 2000 times the mass of an electron.
Step-by-step explanation:
Lets do the division:
Mass of neutron / mass of electron
2 × 10^-24 / 9 x 10^-28
= 0.222 x (10^(-24 - (-28))
= 0.2222... x 10^4
= 2222.
