11 square. units × 7 square. units × 1/2= B. 38.5 square. units.
Answer:
-59
Step-by-step explanation:
x = -2
4(-2)³ - 6(-2)² + (-2) - 1
= -32 - 24 - 2 - 1
= - 59
Answer:
The y-coordinate of B' is equal to 2
Step-by-step explanation:
step 1
Find the distance of AB
step 2
Find the length of A'B'
Multiply the length of AB by the scale factor

step 3
Find the midpoint AB


step 4
<em>Find the x-coordinate of B'</em>
The x-coordinate of B' is equal to the x-coordinate of midpoint plus the semi distance A'B'

<em>Find the y-coordinate of B'</em>
The y-coordinate of B' is equal to 2 (because is a horizontal line)
The answer is 2/5. Divide both the numerator and denominator by 7. :)
Answer:
Function 1 has a greater rate of change.
Step-by-step explanation:
Function 1 has a rate of change of 3 because 3x is the slope of the line.
Function 2 has a rate of change of 1.5, because when you use rise/run, you get a slope of 3/2.
Function 3 has a rate of change of 2. You use the formula (y2 - y1) / (x2 - x1) to find the slope. I used (0,0) and (1,2). When you plug in 2 for y2, 1 for x2, and 0 for y1 and 0 for x1, you get (2-0) / (1-0) which is 2/1. That equals a slope of 2.
