Answer: x = 11
Step-by-step explanation:
same as the last question, set them as equal and solve. here's my work:
<em>5x - 1 = 4x + 10</em>
<em>5x - 1 (+ 1) = 4x + 10 (+ 1)</em>
<em>5x = 4x + 11</em>
<em>5x (- 4x) = 4x (- 4x) + 11</em>
x = 11
Answer:
(i)
time to bounce in one direction is 0.75 sec
(ii)
time to bounce in other direction is 1.5 sec
(iii)
total time is 2.25 sec
Step-by-step explanation:
Time to bounce in one direction:
we can see that height is increasing till t=0.75sec
so, time to bounce in one direction is 0.75 sec
Time to bound in other direction:
we can see that height is decreasing from t=0.75 to 2=2.25 sec
so, time to bounce in other direction is 2.25-0.75
=1.5 sec
Total time :
We know that
total time = (time to bounce in one direction)+(time to bounce in other direction)
now, we can plug values
total time =0.75+1.5=2.25 sec
The first option :
Multiply the first equation by 8 and the second equation by 2
would not result in the elimination of the variables in this system
