Answer:
b
Step-by-step explanation:
Y is three times the value of x , It can be said that y is directly proportional to Y .
Direct proportion is when an increase in the independent variable causes an increase in the dependent variable.
the equation for direct proportion is :
y = bx
y = dependent variable
b = constant
x = independent variable
Answer:
(8,5)
Step-by-step explanation:
5x-2y=30
lets substitute "8" as x and see where that takes us
5(8)-2y=30
40-2y=30
subtract 40 on both sides
-2y=-10
divide by "-2" on both sides
y=5
(8,5) is your answer

Answer:
.
Step-by-step explanation:
Two vectors 
and 
are parallel to one another if and only if the ratio between their corresponding components are equal:
.
Equivalently:
.
For the two vectors in this equation to be parallel to one another:
.
Solve for 
:
.
would be the only valid value of ; no other value would satisfy the equation.
