Answer:
Value of the unknown quantity for which from given equation we get true numerical equality is called root of that equation. Two equations are called equivalent when the multitudes of their roots match, the roots of the first equation are also roots of the second and vice versa. The following rules are valid:
1. If in given equation one expression is substituted with another identity one, we get equation equivalent to the given.
2. If in given equation some expression is transferred from one side to the other with contrary sign, we get equation equivalent to the given.
3. If we multiply or divide both sides of given equation with the same number, different from zero, we get equation equivalent to the given.
Equation of the kind ax+b=0, where a,b are given numbers is called simple equation in reference to the unknown quantity x.
Step-by-step explanation:
Answer:
a) Cat
b) 4 (unless there is a key that says otherwise)
c) 3 more people
Step-by-step explanation:
a) It has the least number of shapes (only 5)
b) Cat has 1 small square which stands for 1 person and 4 small squares put together make a big square so a big square is 4 people. Unless a key says that a small square is more or less 1, then it should be 4.
c) If one big square is 4 people, then there are 10 people for giraffes and 7 people for dogs. 10 - 7 = 3 more people.
Answer:
2
Step-by-step explanation:
The easiest thing is to convert it to an improper fraction.
-2 1/9 turns into -19/9. -4 1/9 turns into -37/9.
-19/9 - (-37/9) here you would add because you are subtracting a negative number.
-19/9 + 37/9 change it to positive and then add.
-19+37=18
it was 18/9. that simplified is 2.
To find it it is
ax^2+bx+c
if the first term (a) is 1 then c=b/2
b=-1/4
(-1/4)/2=-1/4 times 1/2=-1/8
k=-1/8
