Answer:
.
Step-by-step explanation:
Given : -6x² = 3 -4x.
To find : What is the discriminant of the quadratic equation .
Solution : We have given that -6x² = 3 -4x.
Rewrite the equation : -6x²+ 4x -3 = 0.
Standard form of quadratic form : ax²+ bx + c = 0.
Discriminant = .
Then, a = -6 , b =4 , c =-3

Answer:
Pedro got 1520 base hits and Ricky got 1243.
Step-by-step explanation:
This question can be solved by a system of equations.
I am going to say that:
x is the number of base hits that Pedro got.
y is the number of base hits that Ricky got.
Pedro and Ricky got 2673 base hits last season.
This means that
Pedro had 277 more hits than Ricky.
This means that
Replacing in the first equation
Pedro got 1520 base hits and Ricky got 1243.
