Answer:
x + 3 = 7/2
100x = 50
16/x = 24
Step-by-step explanation:
The value of x is 1/2 in the three equations.
The variable x is in the left side of the equations.
Answer:
i believe it’s graph A
Step-by-step explanation:
Answer:
x - 2 => x = 2
x² + 3ax - 2a
=> 2² + 3 × a × 2 - 2 × a
=> 4 + 6a - 2a
=> 4 + 4a
=> 4 ( 1 + a )
★ 1 + a = 0
a = -1
If the discriminant is a positive number, there will be 2 possible solutions. If you replace the entire section of b²-4ac with 16, you will see that the equation becomes; (-b+-√16)/2a --> leading to an answer with the + and another with the -.
If the discriminant is 0, there will be 1 possible solution, (again replace this into the discriminant value) (-b)/2a ---> this formula is used to also find the x coordinates of a vertex, fyi.
If the discriminant is a negative number, there will be no solution (since squareroot of a negative number is not possible)
Hope I helped :)
