Question

In drilling world’s deepest hole, the Kola Superdeep Borehole, the deepest manmade hole on <br /><br />Earth and deepest artificial point on earth, as a result of a scientific drilling project, it was <br /><br />found that the temperature T in degree Celsius, x km below the surface of earth, was given <br /><br />by:<br /><br />T = 30 + 25(x -3), 3 < x < 15.<br /><br />If the required temperature lies between 200℃ and 300℃, then<br /><br /><br /><br /> i the depth, x will lie between<br /><br />a. 9 km and 13 km<br /><br />b. 9.8 km and 13.8 km<br /><br />c. 9.5 km and 13.5 km<br /><br />d. 10 km and 14 km<br /><br /> ii Solve for x: -9x+2 > l8 OR 13x+15 ≤ -4<br /><br />a. x < -19/13<br /><br />b. x < -16/13<br /><br />c. -16/13 < x < -19/13<br /><br />d. There are no solution.<br /><br /> iii. Find the inequality represented by the graph​
