Mathematics
1 answer:
Serhud [2]4 years ago
4 0

Answer:

  • x = -1
  • y = -3

Step-by-step explanation:

Since you have an expression for y, it is convenient to use it.

  -2x + 8(3x) = -22 . . . . . substitute 3x for y in the second equation

  22x = -22 . . . . . simplify

  x = -1 . . . . . . . . . .divide by 22

Substituting this value into the expression for y:

  y = 3(-1) = -3

The solution is (x, y) = (-1, -3).

Logarithmic and Exponential Forms of Equations In Exercise, write the logarithmic equation as an exponential equation, or vice v
marysya [2.9K]

Answer : The logarithmic equation of given exponential equation is, \ln (0.0183)=-4

Step-by-step explanation :

As we are given the exponential equation.

e^{-4}=0.0183

Formula used :

The inverse property of logarithm for the expression \ln e^x is:

\ln e^x=x

Now we have to determine the logarithmic equation of given exponential equation.

e^{-4}=0.0183

Taking natural logarithm both sides as,

\ln e^{-4}=\ln (0.0183)

-4=\ln (0.0183)

\ln (0.0183)=-4

Thus, the logarithmic equation of given exponential equation is, \ln (0.0183)=-4
