Jorge wants to determine the enlarged dimensions of a digital photo to be used as wallpaper on his computer screen. the original photo was 800 pixels wide by 600 pixels high. the new photo will be 1,260 pixels wide. what will the new height be?

Step-by-step explanation:

We know  that the original photo was 800 pixels wide and the new photo will be 1,260 pixels wide. Therefore,  we can find the scale factor.

Divide the width of the new photo by the width of the original photo. Then the scale factor is:

The final step is to multiply the height of the original photo by the scale factor calculated.

Therefore the height of the new photo will be:

Step-by-step explanation:

Givens

First, we need to find the scale factor by dividing

Then, we multiply the height by the scale factor

Therefore, the new height is 945 pixels.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
