Will give medal. c: Compare and Contrast: Two equations are listed below. Solve each equation and compare the solutions. Choose the statement that is true about both solutions. Equation 1 Equation 2 |5x + 6| = 41 |2x + 13| = 28
Go ahead and solve each equation separately. When using absolute bars, you can get rid of it as follows: If |A| = B it means either A = B or A = -B |5x + 6| = 41 means: 5x + 6 = 41 or 5x + 6 = -41 solve each separately.
5x + 6 = 41 - 6 - 6 5x= 35 5x/5 = 35/5 x=7 5x + 6 = -41 - 6 - 6 5x = -35 5x/5= -35/5 x= -7 is this right?
The first one is correct... The 2nd one is set up like this... -(5x + 6) = 41 -5x - 6 = 41 -5x = 41 + 6 -5x = 47 x = -47/5 ============= | 2x + 13 | = 28 2x + 13 = 28 2x = 28 - 13 2x = 15 x = 7.5 -(2x + 13) = 28 -2x - 13 = 28 -2x = 28 + 13 -2x = 41 x = - 20.5 ================= read this... http://www.purplemath.com/modules/solveabs.htm
ohh, my options are worded though
i'll post them now
Eq. 1 has more solutions than Eq. 2 Eq1 and Eq2 have the same number of solutions Eq2 has more solutions than Eq1 The number of solutions cannot be determined
@texaschic101 which would it be? the options is the part that confused me
Look at what you got and what texaschic101 got. Note that equation had two solutions and only two. Equation also had 2 and only 2 solutions. which option fits the situation?
Each equation had 2 and only 2 solutions.
