Starting off, if you understand the quadratic formula (if you don’t look up the formula) you’re looking for A,B, and C. A is 3, B is -4, and C is 11. You would then plug in these numbers following the quadratic formula, which results in;
The first option is the correct one. :)
8 is your answer. You have to set the equations equal to each other and then solve :)
Y= 4x-1
If y is 1, then plug 1 in the equation,
1= 4x-1
Add 1 on both sides,
2= 4x
Divide by 4 on both sides,
x= 4/2
Reduce 4/2 to 1/2
Therefore, x= 1/2
