A cheetah that is running 90 ft./s is 120 feet behind an antelope That is running 60 ft./s how long will it take the cheetah to catch up to the antelope

4 seconds.

Step-by-step explanation:

Let t be the time in seconds when the cheetah catches the antelope.

-Cheetah's speed is 90ft/s and the antelope's is 60ft/s with a 120ft distance between them.

#The expression of the distance of the two when they catch up is;

#Since the distance of the two will be equal at that point:

Hence, the Cheetah catches the antelope after 4 seconds.

i believe that the slope of the line is -5

step-by-step explanation:

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
