The two equations represent the proportional relationship.
y=3x and y=12x are proportional relation ship equations
proportion equations can be defined as
If we change x the y will change in the same proportion.
<h3>What is the proportional relationship?</h3>
Proportional relationships are relationships between two variables where their ratios are equivalent.
Another way to think about them is that, in a proportional relationship, one variable is always a constant value time the other.
That constant is known as the constant of proportionality.
proportional relationship equation contain (0,0) points
If we put x=0
This will give us,y=0
If we put x=0, in y=12x
It will give y=0
put if we put x=0 in
y=3x it will give us y=0
hence these two equations represent the proportional relationship.

Answer:
15x - 2.
Step-by-step explanation:
3x - 1 + 2x + 1 + 4x - 2 + 4x - 4 + 2x + 4
= 15x - 2.
Answer:
-83/20
Step-by-step explanation:
Answer:
r =5 in
Step-by-step explanation:
Area of a circle is given by
A = pi r^2
We know the area and pi
78.5 = 3.14 r^2
Divide by 3.14
78.5/3.14 = 3.14 /3.14 r^2
25 = r^2
Take the square root of each side
sqrt(25) = sqrt(r^2)
5=r
The more observations you make the closer and closer the experimental probability will approach the theoretical probability. In this case the theoretical probability is:
P(HH)=(1/2)(1/2)=1/4
So in 105 trials one would expect to get two heads:
105(1/4)=26.25 times.
