Answer:
No
Step-by-step explanation:
For a proportional relationship :
y = kx
Where , k = constant of proportionality
Taking the first set of data:
x = 50 ; y = 10
10 = 50k
k = 10/ 50 = 1/5
Hence, the proportional equation or relation is :
y = 1/5x
Check if this is true for other data points on the data :
Taking the second data point :
x = 85 ; check if y will be 20
From :
y = 1/5x
y = 1/5*85
y = 85/5
y = 17
Since ;
y value from the equation isn't the same as that in the table, then the table does not show a proportional relationship.
Given:
The points are M(6,16) and Z(-1,14).
To find:
The distance between given points.
Solution:
Distance formula:
So, the distance between two points M(6,16) and Z(-1,14) is
Therefore, the distance between given points is 7.3 units.
Answer:length = 22. And width = 3+ 1/2(22) = 14
