Answer:
I dont understand the qustion? did you answer it?
Step-by-step explanation:
13x+25=0
13x+25-25=0-25 Since two opposites added give zero, remove them from the expression 13x=-25
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

Parallel lines have the same slope. So if a line has a slope of 2, a line parallel to it also has a slope of 2.
Answer:
26.376 because the circumference formula is 2*3.14*radius so the radius of the goal would be 9 because radius is half of diameter which is 18 so 2*3.14*9=56.52 and the basketball's radius would be 4.8 and then 2*3.14*4.8 is 30.144 so the answer is 26.376 hope it helps
