Answer:
That should be the answer
Step-by-step explanation:
the formule is y = mx +b
m is the slope and b is the y-intercept
Answer:
I) no charge
ii) it will be positively charged
iiI) it will be negatively charged
Step-by-step explanation:
An atom is composed of electrons, neutrons and protons. Electrons are negatively charged while protons are positively charged. The number of electrons and protons in a neutral atom are exactly the same. This ensures the electrical neutrality of the atom.
However, if an atom looses an electron, there are now more protons than electrons present in the atom hence the atom is positively charged.
Similarly, if an atom gains an electron, it now contains more electrons than protons, hence it is negatively charged.
Answer:
10 cars
Step-by-step explanation:
volleyball team = past money + money from car wash = 40 + 2 per car = 40 + 2 * number of cars
wrestling team = past money + money from car wash = 50 + 1 * number of cars
set the two equal to each other because they raise the same amount
40 + 2 * number of cars = 50 + 1 * number of cars
set number of cars to n
40 + 2n = 50 + n
subtract n from both sides to put all the variables on one side
40 + n = 50
subtract 40 from both sides to find n
n = 10
The statement <span>The coefficient of x^k y^n-k in the expansion of (x+y)^n equals (n-k / k) is true. This will show the standard formula and the expansion of it. We all know that it can still be expanded based on the power or degree of the terms.</span>
