Answer:
Step-by-step explanation:
We know that the standard quadratic equation is ax^2+bx+c=0
Let's compare all the given equation to it and , find discriminant.
1. a=2, b= -7, c=-9
So it has 2 real number solutions.
2. a=1, b=-4, c=4
So it has only 1 real number solution.
3. a=4, b=-3, c=-1
So it has 2 real number solutions.
4. a=1, b=-2, c=-8
So it has 2 real number solutions.
5. a=3, b=5, c=3
Thus it does not has real solutions.
4200= 4.2 km so
4200 + 325= 4525 meters
jason ran 4525 meters
Answer:
Part 1)
Part 2)
Part 3)
Step-by-step explanation:
we know that
The old account balance plus the transaction amount is equal to the new account balance
The transaction amount can be a positive number (example a deposit) or a negative number (example a withdrawal)
Part 1) Find the value of A
solve for A
subtract 432 both sides
Part 2) Find the value of B
solve for B
Rewrite
Part 3) Find the value of C
solve for C
subtract 52 both sides
