(6x^4) + (15x^3)(y^2) + (3x^2)(y^3) is your answer

As we are looking at descending powers of x. Look at the powers of the x. In the first one (6x^4), the power is 4, and 4 is greater than the other numbers given (3 & 2). Therefore, the order given above is correct.

hope this helps

The slope of a hill next to a highway decreases 2 vertical feet for every 3 horizontal feet away from the highway.
Novay_Z [31]

Slope is the change in Y ( vertical) over the change in X( horizontal).

The slope would be -2 /3

You would multiply the horizontal distance by the slope:

-2/3 x 12 = -8

The answer would be D. v(h)=-2/3h, and the vertical distance is -8 feet.

What key features of a quadratic graph can be identified and how are the graphs affected when constants or coefficients are adde
leonid [27]

The key features of a quadratic graph that can identified are; x and y intercepts, axis of symmetry and vertex

<h3>Keys features of a quadratic graph</h3>

The key features are the x-intercepts, y-intercepts, axis of symmetry, and the vertex.

If we add units we can move this function upwards, downwards leftwards and rightwards.

  • If we add a positive number to the x-variable, then the graph will move to the left.
  • If we add a negative number to the x-variable, then the graph will move to the right.
  • If we add a positive number to y-variable, then the graph will move upwards.
  • If we add a negative number to y-variable, then the graph will move downwards.

Hence, if we compare the rules we use before with linear function, there's no distinction between horizontal and vertical movements, because if we add to x-variable, then y-variable will be also affected.
