Y varies inversely as x. Y=12 when x=7. Find y when x=4
Mar 1, 2022 · If y varies inversely with x, that means that y follows the form: y = a/x. Now, given that y = 12 when x = 7 we just need to plug 12 in for y and 7 in for x into the equation y = a/x and solve for a. Therefore, y = a/x. 12 = a/7; when y = 12 and x = 7. a = 84 (just multiply both sides by 7 to get a alone on one side of the equation).
