A plane is flying from Atlanta to Seattle, approximately 2,150 miles. The plane flies 30 miles beyond Seattle and then is put in a circular holding pattern around the city that can be modeled by y = 2150 + 30cos( π 10 x), where x is the amount of time that has passed and y is the plane's distance from Atlanta. If the plane circled for 50 minutes, how many revolutions did he complete?

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5

a: kite
