The best choice that it would be would be 3
X - 26 = 57
If you were to find what 'x' was it would be 83
Answer:
Step-by-step explanation:
1.75x+1.25y=2 Multiply this equation by 4
7x + 5y = 8
7x+5y=9
As you can see, the xs and ys have the same coefficient. These lines are parallel. There are NO solutions. Just to show you that, here is a graph.
Answer: For the equation simply substitute 30 in for v and 4 in for s in the equation given, so H=-16t^2+30t+4
Part 2.
If the juggler misses the ball, you wish to know the time that it takes for the ball to travel the four feet from his hand to the ground, so respectively,
4=-16t^2+30t+4 or 0=-16t^2+30t or 0 = -16t+30,
solving for t, t =30/16 seconds or 1.875 seconds
