What is the value of the x variable in the solution to the following system of equations? .
2x − 3y = 3
5x − 4y = 4
a.) −1
b.) 0
c.) x can be any number as there are infinitely many solutions to this system
d.) there is no x value as there is no solution to this system

B

Step-by-step explanation:

We need to solve for    here.

Equation 1:  

Equation 2:  

Solving for  in Equation 1 and substituting that into Equation 2 gives us:

Substituting this expression into Equation 2 and solving for  gives us:

 is the solution. Answer choice B is correct.

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
