Step-by-step explanation:
Answer:
The unit rate is -0.5 store per year
Step-by-step explanation:
Let
x -----> the number of years since 1996
y ----> the number of video rental stores
we know that
The year 1996 represent x=0
so
2016 represent ----> x=2016-1996=10 years
we have the points
(0,9) and (10,4)
The unit rate is equal to the slope of the linear equation
<em>Find the slope m</em>
----> is negative because is a decreasing function
therefore
The unit rate is -0.5 store per year
Answer: B: They have different perimeters but the same area.
Explanation:
For the rectangle on top, the perimeter (the lengths of all the sides added together) is 5+4+5+4=18. The area (the length of the base times the length of the height) = 5*4=20.
For the larger rectangle on the bottom, the perimeter would be 10+2+10+2=24. The area of this rectangle would be 10*2=20.
The two rectangles have the same area (20) but not the same perimeter.
Answer:
no option matches this
Step-by-step explanation:
side =s+4.5
perimeter=4(s+4.5)
or=s+4.5+s+4.5+s+4.5+s+4.5
area=(s+4.5)(s+4.5)
Answer:
Yes
Step-by-step explanation:
If the longest side squared is equal to the sum of the squares on the other 2 sides then they form a right triangle
longest side = 7.5
7.5² = 56.25
2.1² + 7.2² = 4.41 + 51.84 = 56.25
Thus the 3 values form a right triangle.
