Kenya is solving the equation 5 34−16x=4 12. She gets to 1 14=16x. Is this a valid way to solve the equation? Yes, because there are still fractions. A Yes, because there are still fractions. B No, because you cannot change the side of the equation that x is on. No, because you cannot change the side of the equation that , x , is on. C Yes, because she subtracts 4 12 from both sides and adds 16x to both sides. Yes, because she subtracts 4 12 from both sides and adds 1 sixth x to both sides. D No, because the coefficient on x has changed from negative to positive.

If a || b and b | y, then ? a) x || y. b) x | a. c) a | y. d) a || y.

In δabc shown below, ∠bac is congruent to ∠bca: triangle abc, where angles a and c are congruent given: base ∠bac and ∠acb are congruent. prove: δabc is an isosceles triangle. when completed (fill in the blanks), the following paragraph proves that line segment ab is congruent to line segment bc making δabc an isosceles triangle. (4 points) construct a perpendicular bisector from point b to line segment ac . label the point of intersection between this perpendicular bisector and line segment ac as point d: m∠bda and m∠bdc is 90° by the definition of a perpendicular bisector. ∠bda is congruent to ∠bdc by the definition of congruent angles. line segment ad is congruent to line segment dc by by the definition of a perpendicular bisector. δbad is congruent to δbcd by the line segment ab is congruent to line segment bc because consequently, δabc is isosceles by definition of an isosceles triangle. 1. corresponding parts of congruent triangles are congruent (cpctc) 2. the definition of a perpendicular bisector 1. the definition of a perpendicular bisector 2. the definition of congruent angles 1. the definition of congruent angles 2. the definition of a perpendicular bisector 1. angle-side-angle (asa) postulate 2. corresponding parts of congruent triangles are congruent (cpctc)
