Hey there!
An equation has a proportional relationship if it fulfills the following:
-Is a linear function, meaning that is is graphed as a line all the way across a graph.
-It goes through the origin. So the point (0,0) has to be one solution to the equation.
That is how you can identify a proportional relation, a linear equations passing through the origin.
Hope this helps!
Step-by-step explanation:
(8.5 cm + 16.4 cm) ÷ 16
= 24.9cm ÷ 16
= 1.25
= 1.25 cm

-3x+6y=5
6x-6y=-6
<span> + -3x+6y=5
</span> 3x = -1
x= -1/3
</span>(-2x+2y=2)/2 -------> -x+y = 1 -------> y = 1+x

Answer:
Rate is 8.5%
Step-by-step explanation:
Step 1: Write the given terms
Principal (p)=Rs8800
Rate(r)=?
Time(t)=3.5 years
Interest=Rs2618
Step 2: Write the formula for calculating Simple interest
Step 3: Make r the subject of the equation
Step 4: Find the value of r by substituting the values in step 1
Hence, the rate is 8.5%
