Answer:
It is not an arithmetic sequence.
Step-by-step explanation:
In an arithmetic sequence, the differences between any two consecutive terms are equal.
7 - 6 = 1
9 - 7 = 2
The differences between two different sets of consecutive terms are different, so it is not an arithmetic sequence.
Answer:
A
Step-by-step explanation:
A solution to a system of linear equations is the point at which they intersect. These graphs do not intersect as they are parallel. There is no solution.
Answer:
x=6
angleC=70 degrees
Step-by-step explanation:
We can utilize the properties of a parallelogram to solve the problem.
First, we know that the two opposite parallel sides of a parallelogram are equal. This gives us the equation
2x+7=19
Solving, we get
2x=12
x=6
We also know that adjacent angles of a parallelogram always add up to 180 degrees. Thus, we get
110+angleC=180
Solving, we get
angleC=180-110
angleC=70 degrees
Answer:
<h3> Mutiplying both sides by 8</h3>
(v/8)×8 = v and 2×8=16 so:
v/8 = 2
v = 16
