To solve the sustem of equations below, kira isolated variable y in the first equation then sybstituted it into the second equation. what was the resulting equation? 3y=12x, x^2+y^2=81

Resulting equation is

Step-by-step explanation:

Isolate y in the  first equation

divide both sides by 3

Now we substitute this value of y into second equation

Hence the resulting equation is

Notice that question doesn't says to solve so there is no need to simplify or solve that equation further

 or   or  

Step-by-step explanation:

Given :

To Find: Kira isolated variable y in the first equation then substituted it into the second equation.what was the resulting equation?

Solution:

  --1

 --2

Value of y from 1

Substitute this value of y in 2

Hence  the resulting equation is  or   or  

(c, 0) i might be wrong so don't put full faith on my answer

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2  

x

x

​    

=240

=48
