Answer:
Step-by-step explanation:
The arithmetic sequence has the form:
When a=10.31, n=9, we substitute to get:
Similarly, when n=13 and a=11.71, we get:
Subtract equation 1 from equation 2 to get:
This implies that
Substitute into the second equation to get:
Solve to get
Hence the explicit formula is:
Answer: D) -2 |x| - 2
<u>Step-by-step explanation:</u>
A v-shaped graph is an absolute value graph.
The general form of an absolute value equation is: y = a |x - h| + k
where (h, k) represents the vertex and "a" represents the vertical stretch (aka slope).
The vertex of the given graph is (0, 2), however the graph is inverted (upside-down) which is a reflection across the x-axis. Therefore,
<h2> --> y = -2 |x| - 2</h2>
75a^2b/25ab^2
= 75x axaxb /25xaxbxb
=3a/b
Answer:
-6x - 3h
Step-by-step explanation:
Write as a function.
Consider the difference quotient formula.
Find the components of the definition.
Plug in the components.
Simplify
-6x - 3h
