Write the direct variation function given that y varies directly with x, and y = 1.5 when x = 5.
1 answer:
Answer:
y=0.3x
Step-by-step explanation:
Formula =
y α x
y = kx
Where k is the constant of proportionality.
When y = 1.5; x = 5;
We substitute these known values in the equation,
y = kx
1.5 = k5
Dividing both sides of the equation by 5 to find the value for k, we have
1.5/5= k0.3/5
Therefore,
K = 0.3
Having found the value of k,
We substitute this value into the relationship
y = kx
Therefore we have,
y = 0.3x.
The direct variation function is therefore,
y = 0.3x.

Answer:
none
Explanation:
Fill in each option for x individually.
I) 9 -10 - 4(-1)
II) 9 -10 - 4(-3)
III) 9 -10 - 4(-2)
Then, simplify the right side of each inequality.
I) 9 -6
II) 9 2
III) 9 -2
Each of these inequalities are flase. 9 is not less than or equal to any of these values, so the answer is none.
