Solve -t/5 > 15 a. t < -75 b. t > -75 c. t < -3 d. t > -3

For this case we must solve the following inequality:

We follow the steps below:

We multiply by 5 on both sides of the inequality:

We multiply by -1 on both sides of the inequality. We must bear in mind, that when multiplying by -1, the sense of the inequality changes.

Option A

step-by-step explanation:

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
