Me with this question i will give brainliest to the correct answer

A)   y= (-1/2)x+50

 (y=(-1/2)4 +50 = -2+50= 48)

Y=( -1/2 )8-50=-4+50 =46

B)    -1/2X+50>=40

         -1/2X>= -10

           X<=20

To start the meeting with 40 students it should be 20 minutes or less before the meeting

 Draw the line with the zero in the middle

Draw a closed circle at +20 and from that point draw a line to the left

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
