Answer:
<em>9.3 + b = 14.5</em>
Step-by-step explanation:
We are learning about perimeter.
Look for the formula of the perimeter,
P = a + b + c
The question states "The longest side is twice that of the shortest side."
A is the longest side while b is the shortest side.
The shortest side equation would be found below :
6.2 = 2c
c = 3.1
Making a completion of the longest side :
14.5 = 6.2 + 3.1 + b
14.5 + 9.3 + b
Yessssssssssssssssssssssss
Relative frequency = (number of times an item appears) /(TOTAL numbers)
Relative frequency (selecting Red ) = 13/30 =0.434
Answer:
b
Step-by-step explanation:
because perimeter of rectangle is 2(l+b)
Answer:
The linear function is
. The graph of function is given below.
Step-by-step explanation:
The slope intercept form of a linear function is
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
Where, m is slope and b is y-intercept.
Since the slope is -1 and the y-intercept is 3, therefore the linear function is,
![y=-x+3](https://tex.z-dn.net/?f=y%3D-x%2B3)
put y=0, to find x-intercept.
![0=-x+3](https://tex.z-dn.net/?f=0%3D-x%2B3)
![x=3](https://tex.z-dn.net/?f=x%3D3)
Therefore the line intersect the y-axis at y=3, x-intercept is x=3 and the as the value of x increases the value of y decreases.
The graph of the linear function
is given below.
