(2x2 + x − 3 )(x − 1.)
= 4x3 + x2 - 3x - 2x2 - x + 3
= 4x3 - x2 - 4x + 3
option 4
Answer:
Which graph could represent a constant balance in a bank account over time? A graph titled Daily Balance.

Answer:
Part A:
c = .86*p
c =1.72 for 2 lbs
Part B:
c =.81p
Step-by-step explanation:
Part A:
Total cost = cost per pound * number of pounds
c = .86*p
Let p = 2
c = .86*2
c =1.72
Part B:
Total cost = cost per pound * number of pounds
c = .(.86-.05)*p
c =.81p
Answer: y-intercept: (0, -0.7) and x-intercept: (-1.2, 0)
Recall: The coordinate of a point is always written as (x,y).
Look to the x- and y-axis and see where there's a point that's exactly on it; that'll be your x- and y-intercept.
The point (0, -0.7) is on the y-axis, so that's your y-intercept. The point (-1.2, 0) is on the x-axis, so that's your x-intercept.
