A proportional relationship can we written as follows:-
y = mx
Where 'y' is dependent variable, 'x' is independent variable, and 'm' is the slope or we can say 'm' is constant of proportionality.
'm' can take any value whether negative or positive, decimal or whole number. 'm' is a real number.
The given problem is y = x/9 and student says we can only multiply constant, and not divide. We disagree with this comment because m= 1/9 is correct.
So y = 1/9 x makes sense.
y = x/9 represents a proportional relationship.
Answer:
B

The vertex is always in the middle.
Answer:
21 and 96
Step-by-step explanation:
Let x and y be the two numbers such that x>y.
As the sum of both the numbers is 96.
x+y=96...(i)
As the larger number is nine less than four times the smaller number,
So, x=4y-9
From equation (i),
4y-9+y=96
5y=96+9=105
So, y=105/5=21
By using equation (i),
x=96-y=96-21=75
Hence, both the numbers are 21 and 96.
Answer:
<h2><em>
60.0m≤60.1m</em></h2>
Step-by-step explanation:
Given the interval for the measurement to be 60 m ± 4.5%, the posible range of each measurement is expressed as shown;
60 m ± 4.5% = 60 m ± 4.5/100
= 60 m ± 0.045
= (60 - 0.045, 60+0.045)
= (59.955, 60.045)
<em>Hence possible range of each measurement to the nearest tenth is (60.0m≤60.1m)</em>
