When a number is doubled and then taken away from ten, the result is negative eighteen. What is the number?

14

Step-by-step explana:

Let the required number be x

Therefore, according to the given condition:

10 - 2x = - 18

10 + 18 = 2x

28 = 2x

x = 28/2

x = 14

Hence, the required number is 14.

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).
