What is the definition of a relation?
Minchanka [31]

Answer:

i did not understant your question

i think u want the definition of relation

A relation between two sets is a collection of ordered pairs containing one object from each set. If the object x is from the first set and the object y is from the second set, then the objects are said to be related if the ordered pair (x,y) is in the relation. A function is a type of relation.

Match the reasons with the statements. GIVEN: x2 + 6x + 2x + 12 = 0 TO PROVE: x = -6 or x = -2 1. x2 + 6x + 2x + 12 = 0 Subtract
mestny [16]

Given: x^2 + 6x + 2x + 12 = 0.

1. Combining like terms (here terms 6x and 2x both contain x, then we can combine them):

x^2+(6x+2x)+12=0,\\\\x^2+8x+12=0.

2. Distributive postulate:

x^2+8x+12=(x+6)(x+2).

The equation is

(x+6)(x+2)=0.

3. Zero product postulate (zero product postulate state that if a product of two factors is equal to zero, then first factor is equal to zero or second factor is equal to zero):

x+6=0 \text{ or } x+2=0.

4. Subtraction property of equality:

a) subtract 6 from the first equation:

x+6=0\Rightarrow x+6-6=-6, \ x=-6.

b) subtract 2 from the second equation:

x+2=0\Rightarrow x+2-2=-2, \ x=-2.

Triangle - Find Value of X
ira [324]

Answer:

This is an isosceles triangle. You should know that in an isosceles triangle, 2 sides are the same if the opposite side lengths are the same. So 4x-2=62. Then   add 2 to both sides to get 4x=64, and finally divide by 4 to get the answer of 16. x=16
