What solution do 2x2 - 13x + 21 = 0 and 2x2 + 9x - 56 = 0 have in common? Round your answer to the nearest tenth if necessary.
lys-0071 [83]
So if we want to know the common solution(s) to a system of 2 equations, So we can just set both equations equal to each other and solve for the x value(s). That’s where I start below;

2x^2-13x+21 = 2x^2+9x-56
2x^2 cancels out and moving everything to one side and anything with an x variable to the other side we have then;
-22x=-77
22x=77 by cancelling the negative signs
x=77/22 therefore x=7/2 or 3.5

Hope this helps you. Any questions please ask.

Which logarithmic equation is equivalent to the exponential equation below?
anzhelika [568]

Answer:

log_e^{67.21}= a

Step-by-step explanation:

The equation is ,

\implies 67.21 = e^a

  • Here e is the Euler's Number . The log which are defined on the base e are called Natural logarithms.

Say if we have a expoteintial equation ,

\implies a^m = n

In logarithmic form it is ,

\implies log_a^n = m

Similarly our required answer will be ,

\implies\boxed{ log_e^{67.21}= a  }
