I attached the picture associated with this question.
Answer:x = 2
y = 5
Explanation:ABCD is a parallelogram. This means that each two opposite sides are equal.
This means that:1- AB = CD2y + 1 = 7x - 3 ...........> equation I
2- AD = BC3x = y + 1
This can be rewritten as:y = 3x - 1............> equation II
Substitute with equation II in equation I and solve for x as follows:2y + 1 = 7x - 3 ...........> equation I
2(3x - 1) + 1 = 7x - 3
6x - 2 + 1 = 7x - 3
6x - 1 = 7x - 3
7x - 6x = -1 + 3
x = 2
Substitute with x in equation I to get y as follows:y = 3x - 1
y = 3(2) - 1
y = 6 - 1
y = 5
Hope this helps :)
6 x 6 = 36
6 + 6 = 12
The answer is 6.
A1=2*5^(1-1)
a1=2,
ratio is 5
so correct answers is A

Step-by-step explanation:
Answer:
The cost in 7 years will be of $384.69.
Step-by-step explanation:
Equation for exponential decay:
The equation for an amount after t years is given by:
In which A(0) is the initial value and r is the decay rate.
The cost of High Definition television now averages $1200, but the cost is decreasing by about 15% percent per year.
This means that . So
What will the cost be in 7 years?
This is A(7).
The cost in 7 years will be of $384.69.
