Answer:
[f(1) - f(3)] / [1–3]
Step-by-step explanation:
<u>Formula</u>
f(x) = 6(2.5)
<u>How to find</u>
The average rate of change over the interval [a,b], or the secant line between the points a and b on the function f(x), is [f(a) - f(b)]/[a-b]. So, substitute a for 1 and b for 3, and you get [f(1) - f(3)] / [1–3]. The quotient of that is your average rate of change.
Sell price = wholesale cost x (1 + markup percentage)
Sell price = 67 x (1+ 0.40)
Sell price = 67 + 1.40
Sell price = $93.80
Answer: Graph is below
=============================================================
Explanation:
We divide both sides by -4 to isolate p. This will flip the inequality sign.
-16 > -4p
-16/(-4) < -4p/(-4)
4 < p
p > 4
The graph has an open hole at 4 and shading to the right. See below.
First, let's prove that triangle ABC and AFG are similar.
Line segment FG and BC are parallel to each other, that's a given.
With this information, we can state that these sides are similar to each other since you can transform BC on to FG using only rigid transformations and dilations.
Another thing is that both of these triangles share angle A, that's a given. Therefore, using the SA similar theorem, we can conclude that these triangles are similar.
Now that we know that triangle ABC and AFG are similar we may start going to the answer box.
We can eliminate the first three answer choices for having sides we cannot make full conclusions due to limited knowledge.
The only answer remaining is the fourth choice.
Yes, no two ordered pairs in this list has the same first element
Remember the x-value is the important one, if there are repeated x-values then it is not a function but rather a relation...
Hope this helps :)
