Are the graph of 4x-3y=9 and y=3/4x+7 parallel, perpendicular, or neither? Explain.

Neither

Step-by-step explanation:

In this question, we have to verify if the equations are parallel, perpendicular, or neither to each other.

Turn the first equation into slope-intercept form so we can get a better understanding:

4x - 3y = 9

Subtract 4x from both sides.

-3y = -4x + 9

Divide both sides by -3.

y = 4/3x - 3

Now lets compare both lines:

y = 4/3x - 3

y = 3/4x + 7

Since the slopes have to be the same in order for the lines to be parallel, we can see that the lines are NOT parallel.

We also know that in order for the lines to be perpendicular, one has to be positive and the other has to be negative. In this case, they both are positive. This means that the lines are NOT perpendicular.

This means that our answer would be neither.

answer: the sun

explanation:

water cycle describes the evaporation of water from earth's surface, formation of clouds and precipitation water back onto the surface of earth. seventy percent of the earth is covered with water in the form of seas and oceans. the heat of the sun causes the evaporation of water from the surface of the ocean. the water vapors rise and condense to form water droplets. the collection of these water droplets form clouds which rain down again.

the evaporation of the oceans surface water as part of the water cycle is caused by the sun
