Answer:
We can say that the no.s are X and form the following equation:
X × (X + 2) = 440
2x = 440-2=438
x = 438/2
x= 219
x+2=219+2= 221
Answer:
The table represents a proportional relationship
Step-by-step explanation:
Given
x ------ y
1 ------- 15
2 --------30
4 ---------60
5 -------- 75
Required
Determine if the table shows a proportional relationship
To check this, we make use of the following formula;
Where k is the proportionality constant
When x = 1, y = 15
When x = 2, y = 30
When x = 4, y = 60
When x = 5, y = 75
Since the value of k for all values of x and y is the same; i.e. 15
Then, the table represents a proportional relationship
