Answer:
x=5/3, y= 4 2/3
Step-by-step explanation:
y=4x−2
y=x+3
x+3=4x-2
3=3x-2
5=3x
x=5/3
y=4(5/3)−2
y=6 2/3-2
y= 4 2/3
Answer:
Constant of proportionality(X:Y) = 1:6
Step-by-step explanation:
Given:
X- 5, 6, 7, 8, 9
Y- 30, 36, 42, 48, 54
Find:
Constant of proportionality
Computation:
X/Y = 5/30 = 6/36 = 7/42 = 8/48 = 9/54
X/Y = 1/6 = 1/6 = 1/6 = 1/6 = 1/6
So;
Constant of proportionality(X:Y) = 1:6
