For the following true conditional statement, write the converse. if the converse is also true, combine the statements as a biconditional. if x = 7, then x2 = 49. a. if x2 = 49, then x = 7. true; x^2 = 49 if and only if x = 7. b. if x2 = 49, then x = 7. true; x = 7 if and only if x^2 = 49. c. if x2 = 49, then x = 7. false d. if x2 = 7, then x = 49. false

If f(x) = 4x – 3 and g(x) = 8x + 2, find each function value a.f[g(3)] b.g[f(5)] c.g{f[g(-4)]}

Circle d circumscribes abc and abe. which statements about the triangles are true? statement i: the perpendicular bisectors of abc intersect at the same point as those of abe. statement ii: the distance from c to d is the same as the distance from d to e. statement iii: bisects cde. statement iv: the angle bisectors of abc intersect at the same point as those of abe. a. i only b. i and ii c. ii and iv d. i and iii e. iii and iv

Arefrigeration system at your company uses temperature sensors fixed to read celsius (°c) values, but the system operators in your control room understand only the fahrenheit scale. you have been asked to make a fahrenheit (°f) label for the high temperature alarm, which is set to ring whenever the system temperature rises above –10°c. what fahrenheit value should you write on the label?
