A hot air balloon is 10 meters above the ground and rising at a rate of 10.5 meters per minute. Another balloon is 250 meters above the ground and descending at a rate of 14 meters per minute.

a. Define variables for this problem.

x =

y =

b. Write a system of equations to represent the height of the balloons at any given time.

c. Put the equations into a graphing calculator. Use the calculator to solve the system of equations.

d. Explain what the solution means in the context of this problem.

I managed to get the variables down but the rest of the problem has me confused. I would really appreciate any help on this problem.

answer:   rotate 270° clockwise about (7, 1) and reflect across the line x = 7

step-by-step explanation:

because i took test

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system

replace   with   27   and simplify.

10 , 27 , 10 , 70 , 10 , 35 , 10 , 48

step-by-step explanation:

the correct answer option is d. la = πrs.

step-by-step explanation:

we know that for a right cone, the lateral surface area is given by:

lateral area of right cone =

here the value under the square root is equal to slant height so replacing this value by in the formula to get:

lateral area of right cone =

therefore, the correct answer option is d.
