Answer:
a = 9
Step-by-step explanation:
you can simplify the proportion to:

use cross- multiplication
8a = 72
a = 9
Y=1/3x+1 is the equation for ur question
As, v=√2as
Squaring both sides,
v²=2as
∴ s= v²/2a
20
Constant in a mathematical expression is a term whose value never changes.
The terms with x and y will vary based on the variable x and or y.
