Using the equation y=kx and the table below, find the constant of proportionality (k).
2 answers:
Answer:
k = 9/4
Step-by-step explanation:
Here , we have given equation and we need to find k.
To find k, we have given equation which is y = kx
pick any point from the table and substitute in the equation.
y = kx
We choose :- x = 8 and y = 18
18 = 8 × k
Divide each side by 8
18/8 = k
9 / 4 = k
Answer:
k = 9/4
Step-by-step explanation:
To find k, use the equation
y = kx
Pick a point
72 = k *32
Divide each side by 32
72/32 = k
9/4 = k

Answer:
D
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
= 
, substitute values
= 
( cross- multiply )
x² = 39 ( take the square root of both sides )
x = 
→ D
Answer:
A
Step-by-step explanation:
D is correct. The median is 28, Q1 is 22, Q3 is 38
They are equal so...
15x+2 = 9x+20
15x-9x = 20-2
6x =18
x = 18/6 = 3
x = 3
