Find the extraneous solution of the equation |2x−10|=−3x

1 answer:

5 0

|2x - 10| = -3x
Open absolute value symbol
2x - 10 = 3x
OR
2x - 10 = -3x

x = -10
OR
x = 2

Plug them in...
|2(-10) - 10| = -3(-10)
30 = 30
x = -10 is not the extraneous solution.

|2(2) - 10| = -3(2)
6 ≠ -6
x=2 is the extraneous solution.
Have an awesome day! :)

Hi there
The formula of the future value of annuity ordinary is
Fv=pmt [(1+r/k)^(kn)-1)÷(r/k)]
Fv future value?
PMT monthly payment 608
R interest rate 0.06
K compounded monthly 12
N time 6years
So
Fv=608×(((1+0.06÷12)^(12×6)
−1)÷(0.06÷12))
=52,536.58...answer

Good luck!

Combine like terms
8u+3u= 11u
and
9v-5v= 4v
So the answer is 11u+4v
