Answer:
No.
The first term can be represented as , whereas the second term can be represented as . In the first term, we are only multiplying 9 by m, and in the second term we are multiplying 9 by m, and by n.
Explanation: Here we have function f(x) = 2x - 5
and we're asked to find f(x - 1).
Don't be thrown off if you're asked to plus a variable into a function.
If f(x) = 2x - 5, then f(x - 1) = 2(x - 1) - 5.
<em>Remember to use parenthses when substituting into a function.</em>
So simplifying on the right side, we would distribute the 2
through the parenthses and we have 2x -2 - 5.
Now combining like terms, we have 2x - 7
I didn’t see your full question but I’ve seen the same question before. If I’m correct, it should be 5/12 x 192 = 80. So she would put $80 in her savings account.
Given:
Two electrons are added to each of six atoms in a group.
To find:
The expression for the net change in charge.
Solution:
Charge of atoms = Number protons - Number of electrons.
Let number of atoms be x.
6 atoms = 2 electrons added
1 atom = electrons added
1 atom = electrons added
x atoms = electrons added
Therefore, the net change in charge is represented by the expression because we subtract number of electrons to find atom charge, where, x is the number of atoms.
6 atoms = 2 protons removed
1 atom = protons removed
1 atom = protons removed
x atoms = protons removed
Therefore, the net change in charge is represented by the expression , where, x is the number of atoms.
X= -7
2+x=-5 if you move the constant to the right side it would be x=-5-2 which equals -7
