Answer:
check the last 2 in each section
Step-by-step explanation:
when you multiply both sides of an inequality, you have to switch the signs. so > would become <, and vice versa.
Answer:
None of them.
Step-by-step explanation:
Each and every straight line is of one kind in terms of its pattern: it can be presented in the view of 
: 
is the slope or gradient of the line, 
is the y-intercept of the line. I will not let the cat out of the bag if I say that any parallel lines do not intersect one another, hence they should have the same value of coefficient .
Therefore, our line has 
and 
coefficients.
(A) 
(B) 
(С) 
(D)
Recapitulating this: none of them have the same coefficient , thus none of them suit us.
Answer:
Symmetric property
Step-by-step explanation:
In this question, we are given a set of options to choose the correct answer from which gives the definition of the property in the question.
The correct answer here is the symmetric property. So why is this correct?
In proper terms, we refer to this property as the symmetric property of congruence.
It is a way of referring to the fact that when writing the way two congruent angles are equal to each other by the property of congruence, we can move in either of the two directions.
Either way we write, we are absolutely correct to indicate that both angles are equal due to the property of congruence.
A₁ = 9
a₂ = 9+2 → a₂ = a₁ + 2. Since it's an AP, d, the common difference is 2
1) Then the recursive formula is :
a(n) = a(n-1) + 2
2) Explicit formula:
It's an AP, with first term a₁, d= common difference and n = number of term, which is the number of rows in this problem.
the value of the nth term is given by the formula is:
value of nth term = a₁ + (n-1).d
3) Number of seats in the 12th row:
9 + (12-1).2 = 31 seats
For this case we have that by definition, a function is of the form:
So, we have the following system of equations:
Equating the equations we have:
Adding 2x to both sides of the equation:
Subtracting 2 from both sides of the equation:
Dividing between -4 on both sides of the equation:
Thus, the value of the variable "x" is -0.5.
Answer:
-0.5
