The graph shows two lines, a and b. a coordinate plane is shown with two lines, a and b, graphed. line a has a slope of negative 1 and crosses the y axis at 5. line b has a slope of positive 1 and crosses the y axis at 3. how many solutions are there for the pair of equations for lines a and b? explain your answer.

There is one/unique solution to the pair of equations for line A and line B.

We know that the equation of a line in slope intercept form is given by:

                     y= mx+b

where m is the slope of the line and b is the y-intercept of the line.

The graph A:

  Line A has a slope of negative 1 and crosses the y axis at 5.

i.e. the slope of line i.e. m= -1

and y-intercept of line i.e. b=5

Hence, the equation of line A is:

              y= -x+5

Graph B:

Line B has a slope of positive 1 and crosses the y axis at 3.

i.e.  m=1

and b=3

Hence, the equation of line B is:

               y=x+3

Now from the graph of these two lines we see that the system of lines intersect at just one point.

       Hence, there is just one solution for the pair of equations.

replace   with   27   and simplify.

step-by-step explanation:

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
