Answer:
Step-by-step explanation:
if you're saying she ran .2 miles in 12 hours
then she ran .016 miles per hour
if you're saying she ran 2 miles in 12 hours,
then she ran 1/3 mile per hour or 0.3333 miles per hour

Step-by-step explanation:
1 = B
4-(-3) that 3 is turned into a positive number
2 is b same reason
Y = 4x - 3 - x^2
now sub that in for y in the other equation
x + y = 1
x + 4x - 3 - x^2 = 1
-x^2 + 5x - 4 = 0
(-x + 1)(x - 4) = 0
-x + 1 = 0 y = 4x - 3 - x^2
-x = -1 y = 4(1) - 3 - 1^2
x = 1 y = 4 - 3 - 1 = 0
x - 4 = 0 y = 4x - 3 - x^2
x = 4 y = 4(4) - 3 - 4^2
y = 16 - 3 - 16
y = -3
points that satisfy this are : (1,0) and (4,-3)
Answer: Second option.
Step-by-step explanation:
By defintion, a Quadratic function is a polynomial of degree 2 and it has the following form:
Therefore, the function given is Quadratic. This is:
The steps to find the roots (or the x-intercepts) of the function, are:
1. You must substitute 
:
2. Now, you can factor the Quadratic equation. Choose two numbers whose sum is 6 and whose product is 9. Notice that:
Therefore, you will get a "Double root".
4. So the solution is:
