Answer:
3.6
Step-by-step explanation:
To find f(2.6), you simply have to plug in 2.6 for every x in the equation. So, your new equation should be [2.6] + 1 = f(x). From there, you simply add the two together to come up with 3.6.
The length of A"B" is 20 units
<h3>How to determine the length of A'B'?</h3>
From the figure, we have:
A = (1, 4)
B = (4, 8)
The distance AB is:
So, we have:
Evaluate
This gives
AB = 5
The scale factor of dilation is 4.
So, we have:
A'B' = 5 * 4
Evaluate
A'B' = 20
Hence, the length of A"B" is 20 units

Answer:
-6
Step-by-step explanation:
The average rate of change of a function, f(x), on interval [a,b] is (f(b)-f(a))/(b-a).
So the avereage rate of change of a function, f(x)=x^2+5x+1, on [-9,-2] is
(f(-2)-f(-9))/(-2--9)
(f(-2)-f(-9))/(7)
Stop!
To find f(-2), you replace x in f(x) = x^2 + 5x + 1, with (-2) giving you f(-2)=(-2)^2+5(-2)+1=4-10+1=-6+1=-5.
To find f(-9), you replace x in f(x) = x^2 + 5x + 1, with (-9) giving you f(-2)=(-9)^2+5(-9)+1=81-45+1=36+1=37.
Continue!
(f(-2)-f(-9))/(7)
=(-5-37)/7
=(-42)/7
=-42/7
=-6

Answer:
5 and -6.
Step-by-step explanation:
When you add 5 and -6, you get -1. When they are multiplied, you get -30. I just did this by finding all of the factors that went into 30 and making one negative.
