(4p +3)(5p2 + 6) is your answer
1. Eyeballing the data, the best fit will be pretty close to a line between the leftmost point and the rightmost point.
We estimate those points as (4,220) and (28,470)
The point point form for a line joining (a,b) and (c,d) is
(c-a)(y-b) = (d-b)(x-a)
(28 - 4)(y - 220) = (470 - 220)(x - 4)
24(y - 220) = 250(x-4)
24y - 5280 = 250x - 1000
24y = 250 x + 4280
y = (250/24) x+ (4280/24)
Approximately that's,
y = 10.4 x + 178
Answer: 4th choice, 10.4x + 180
2. For 48 wheelbarrows,
y = 10.4(48)+180 = 679.2
Answer: 679.2 liters of sand
The answer is y= -3x-3

Answer is 43 degrees for #6, and selection C for #7
Answer:
3/12
Step-by-step explanation:
6/12 - 5/12 + 4/12 - 3/12 + 2/12 - 1/12
6 - 5 + 4 - 3 + 2 - 1 =
1 + 4 -3 + 2 - 1=
5 - 3 + 2 - 1=
2 + 2 - 1=
4 - 1=
3=
