Answer:
A
Step-by-step explanation:
Let's first define what exactly the values of a, b, and c represent.
- a: this is the coefficient of the x^2 term
- b: this is the coefficient of the x term
- c: this is the constant term (no variable attached)
Our equation is: y = 7x^2 - 3x + 9.
The coefficient of x^2 is 7, so a = 7. The coefficient of x is -3, so b = -3. And finally, the constant term is 9, so c = 9.
Thus, the answer is A.
2 miles = 3,520 yards
first we need to find how many yards she's walked already :
400×5=2,000 yards
now subtract :
3,520-2,000= 1,520 yards
Keisha needs to walk 1,520 more yards to complete 2 miles
hope this helped
