Y is directly proportianal to x when y is 30 x is 6. work out the equation connecting y and x
labwork [276]

Answer:

Step-by-step explanation:

Solution

The general equation for this kind of problem is

y = k x

30 = k * 6                Divide both sides by 6

30/6 = 6k/6             Combine

5 = k

So the connection between x and y is that to get a value for y, you must divide it by 6.

Suppose you start at the origin, move along the x-axis a distance of 7 units in the positive direction, and then move downward p
Andru [333]

Answer:

The coordinates of your position are x=7, y=0 and z=-2 or in coordinates notation the point given by (7, 0, -2)

Step-by-step explanation:

Since you are starting from the origin of a coordinate system, the coordinates of you position are simply going to be how many units you have moved in each direction.

  1. 7 units in the positive x-axis direction gives you x=7
  2. Then, being in the x-axis, you move 2 units downward parallel to the z-axis. Here the downward gives you a negative sign for the z coordinate, hence, z=-2.
  3. Now, y=0 is given due to the fact that there is no movement in the y-axis direction or you can also say that all the movement have been perpendicular to the y-axis and therefore, your position in this axis is zero.

Find the nonpermissible replacement for y in this expression y-7/y+9
Vesnalui [34]

Answer:

y ≠ - 9

Step-by-step explanation:

the denominator of the expression cannot equal zero as this would make the expression undefined. Equating the denominator to zero and solving gives the value that y cannot be

solve y + 9 = 0 ⇒ y = - 9 ← not permissable
