Answer:
A(2,5)
Step-by-step explanation:
x=2 and y=5
2y+4x=18
2y-3x=4
2(5) + 4(2) = 18
10+8=18
2(5)-3(2)=4
10-6=4
Answer:
Part 1) 
Part 2) 
Step-by-step explanation:
<u><em>The correct question is</em></u>
1) Suppose y varies directly as x, and y equals nine when x equals three seconds. Find y when x equals one
2) Suppose y varies directly as x, and y equals nine when x equals three seconds. Find x when y equals one
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or 
Part 1) we have that
For x=3, y=9
Find the value of k
substitute the value of x and y
----> 
the linear equation is

so
For x=1
substitute in the linear equation and solve for y

Part 2) we have that
For x=3, y=9
Find the value of k
substitute the value of x and y
----> 
the linear equation is

so
For y=1
substitute in the linear equation and solve for x

Divide by 3 both sides
