Answer:
47%
Step-by-step explanation:
We can find the percent of the daily allowance by finding what percent 30 is of 64:
30/64 = 0.468 or approx. 47%
-1/3
Taking two points on the graph (I took (0,9) and (6,7)
Slope=(y2-y1)/(x2-x1)
(7-9)/(6-0)=-2/6
=-1/3
4x^2+4x-4
8x^2 + 3x - 4x^2 + x - 4
= 8x^2 - 4x^2 + 3x + x - 4
= 4x^2 + 4x - 4
