2. Which equation is the direct linear variation equation for the relationship? y varies directly with x and y = 10 when x = 2 A. y = x + 8 B. y = 5x C. y = x - 8
Answers
Inverse variation means y = k/x
For the first question y = kx
We are told y = 10 when x = 2
Therefore 10 = 2k k= 5
which is 5x not x-8

Mrs. Blake needs to hire a babysitter. Kelsey charges $6 per hour plus a $5 fee. Lauren charges $4 per hour, plus a $10 fee. Mrs. Blake set up this equation to figure out for what amount of time both babysitters charge the same.6h + 5 = 4h + 10 What is the correct sequence of steps to solve Mrs. Blake’s equation? A. Subtract 6h from both sides. Subtract 5 from both sides. Divide each side by –2. B. Subtract 4h from both sides. Subtract 5 from both sides. Divide each side by 2. C. Subtract 4h from both sides. Add 5 to both sides. Divide each side by 2. D. Subtract 4h from both sides. Subtract 5 from both sides. Divide each side by 6.

The equation w = 10.8t is a proportional equation where the constant of proportionality is 10.8.
What is an equation?
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4 = 9 is an equation.
We have,
w = 10.8t
Where w is the number of wielding tasks and t is the time it takes.
Now,
W is proportional to t.
The constant of proportionality is 10.8.
Thus,
The number of welding is proportional to the time it takes.

line d.
plane Q.
Answers
Answer:
The only figure that could be parallel to line c is line d
Step-by-step explanation:
Parallel lines : Lines are called parallel if they are always the same distance apart , and will never meet.
Now consider the two planes
Now observer the line c
We are supposed to find the only figure that could be parallel to line c
So by definition
Line d is parallel to line c
So, Option C is true
Hence the only figure that could be parallel to line c is line d
Answer:
Line D
