Hello from MrBillDoesMath!
Answer:
a(n) = 12 - 3(n-1) , n = 1,2,3.,,
Discussion:
The terms are 12, 9, 6, 3 so we are apparently subtracting 3 from each succeeding term. . Hence
a(n) = 12 - 3(n-1) , n = 1,2,3.,,
Thank you,
MrB
Answer:
y = -5(x +6) -9
Step-by-step explanation:
The point-slope form of the equation for a line can be written as ...
y = m(x -h) +k
for a line with slope m through point (h, k).
You have m=-5 and (h, k) = (-6, -9). Filling in these values gives ...
y = -5(x -(-6)) -9
Simplifying a bit, you get ...
y = -5(x +6) -9
The line that maps a figure onto itself is a line of symmetry of the figure.
From the given trapezoid, the line of symmetry of the trapezoid is x = -2.
Therefore, the <span>equation for the line of reflection that maps the trapezoid onto itself</span> is x = -2.
5 is 33 because the question ends up being 14+3+16
Here are a few rules you need to know for this equation:
- Multiplying exponents of the same base:
- Dividing exponents of the same base:
- Turning a negative exponent to a positive one:
So this is our algebraic expression: 
Firstly, multiply 3^-4 and 3^2: 
Next, divide:
Next, turn the negative exponent into a positive one: 
<u>Your final answer is 3/2, or 1.5.</u>
