Answer:
Step-by-step explanation:
y ∞ 1/x
y = k/x
Where k is the constant of proportionality
When x = 3 and y = 5
5 = k/3
Cross multiply
k = 5×3
k = 15
The equation is y = 15/x
Answer: 12 square feet
Step-by-step explanation:
The formula for calculating the area of a triangle is given as :
Area =
x base x height
height = 3 feet
base = 8 feet
substituting into the formula , we have :
Area =
x 8 x 3
Area = 4 x 3
Area = 12 square feet
Therefore : the area of the sign in square feet = 12
Answer:
no, it is not a proportional relationship.
Step-by-step explanation:
if you divide 315 by 175 you get 1.8
if you multiply 315 by 1.8, you don’t get 420. therefore this is not a proportionally relationship.

Answer:
So we must determine the distance between our two given points and that can be found using the distance formula
.
Plugging the values into the equation and solve
![d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%28x_2-x_1%29%5E2%2B%28y_2-y_1%29%5E2%7D)
![d=\sqrt{(-9-5)^2+(-2-6)^2}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%28-9-5%29%5E2%2B%28-2-6%29%5E2%7D)
![d=\sqrt{(-14)^2+(-8)^2}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%28-14%29%5E2%2B%28-8%29%5E2%7D)
![d=\sqrt{196+64}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B196%2B64%7D)
![d=\sqrt{260}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B260%7D)
![d=16.125\ units](https://tex.z-dn.net/?f=d%3D16.125%5C%20units)
Therefore, our final answer is that the distance is 16.125 units
