D. 2.888 in plato the right answer
Answer:
-2 1/4
The average change in the field position run was -2 1/4 yards
Answer:
c = 
Step-by-step explanation:
Given
x² - x + c
To complete the square
add ( half the coefficient of the x- term )² to x² - x
x² + 2(-
)x +
= (x - )² ← a perfect square
with c =
First find the slope of the line that passes through (4,-1) and (-2,3) by calculating "change in y" / "change in x"
So slope = -4/6 = -2/3
Remember the format y = mx + b?
So pick any of the two coordinates (I'll use (4,-1)) and sub in what you can.
-1 = -2/3(4) + b
Solve for b and you'll get 1.66666.... aka 1 2/3
So the equation is y = -2/3x + 5/3
Now for the next question.
So 5/2.5 = y/10
cross multiply and simplify and you'll get y = 20
