The constant of proportionality k is 3.5
Step-by-step explanation:
Proportionality describes any relationship that is always in the same
ratio
If two quantities x and y are in proportionality, then
1. y ∝ x
2. y = k x , where k is the constant of proportionality
∵ x ⇒ 6 , 7 , 8 , 9
∵ y ⇒ 21 , 24.5 , 28 , 31.5
∵ y ∝ x
∴ y = k x
- Use x = 6 and y = 21 to find the value of k
∵ x = 6 and y = 21
∴ 21 = k (6)
- Divide both sides by 6
∴ k = 3.5
- Use x = 7 and y = 24.5 to find the value of k
∵ x = 7 and y = 24.5
∴ 24.5 = k (7)
- Divide both sides by 7
∴ k = 3.5
- Use x = 8 and y = 28 to find the value of k
∵ x = 8 and y = 28
∴ 28 = k (8)
- Divide both sides by 8
∴ k = 3.5
- Use x = 9 and y = 31.5 to find the value of k
∵ x = 9 and y = 31.5
∴ 31.5 = k (9)
- Divide both sides by 9
∴ k = 3.5
The constant of proportionality k is 3.5

Answer:
D. -5
Step-by-step explanation:
The x-intercept is the point at which the graph crosses the x-axis.
Answer:
If the third side is x, then
The perimeter is 5+19+x.
But every side must be less than the sum of the other
two sides, so x < 5+19
x < 24
Adding 5+19 to both sides to make the left side
equal to the perimeter
perimeter = x+5+19 < 24+5+19 = 48
So 48 is the smallest whole number that is larger than the
perimeter of any triangle with a side length of 5 and a side
length of 19.
