line segment JK,Modifying above upper L upper J with bar, Modifying above Upper L Upper K with bar
<u>1. </u>Subtract 24 from both sides
-3x = -27 - 24
Simplify -27 - 24 to -51
-3x = -51
Divide both sides by -3
x = -51/-3
Two negatives make a positive
x = 51/3
Simplify 51/3 to 17
<u>x = 17</u>
<u>2.</u> Regroup terms
n/5 - 17 = 33
Add 17 to both sides
n/5 = 33 + 17
Simplify 33 + 17 to 50
n/5 = 50
Multiply both sides by 5
n = 50 * 5
Simplify 50 * 5 to 250
<u>n = 250</u>
The activity series is an arrangement of species in order of reactivity.
<h3>What is the activity series?</h3>
The activity series is an arrangement of species in order of reactivity. The position of a specie in the series determines the possibility of certain reactions.
The following are the fates of these reactions;
- 2NaBr + I2--------->2NaI + Br2 - Not possible
- 2Fe + Al2O3 ----------> 2Al + Fe2O3 - Not possible
- 2AgNO3 + Ni ----------> Ni(NO3)2 + 2Ag - possible
- Pb + Zn(C2H3O2)2 ----------> Zn + Pb(C2H3O2)2 - Not possible

To find the factor a a polynomial from its roots, we are going to seat each one of the roots equal to
, and then we are going to factor backwards.
We know for our problem that one of the roots of our polynomial is -3, so lets set -3 equal to
and factor backwards:
is a factor of our polynomial.
We also know that another root of our polynomial is
, so lets set
equal to
and factor backwards:
(
is a factor of our polynomial.
We can conclude that there is no correct answer in your given choices.
Answer:
you have to use the slope equation, which is (y2-y1) / (x2-x1)
3. (5-0)/(1 -(-8))
5/1+8
5/9
4. (3-3)/(-4 -8)
0/-12
the slope is 0
6. (-2-8)/(1-0.5)
-10/0.5
-20
7. (7-(-1))/ (4-4)
7+1/0
8/0
the slope is undefined
