B. (−3, 2)
I think
so plz have a good rest of ur day
Answer:
29
Step-by-step explanation:
(c − b)^2 + a^2
Let a = –5, b = –2, and c = –4.
(-4--2)^2 + (-5)^2
(-4+2)^2 + (-5)^2
(-2)^2+ (-5)^2
4 +25
29
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
To find the scaled version of this rectangle by 1/2, start by identifying what this scale factor does to effect the numbers.
In this case, it causes each to divide by two.
Divide each value on the length and width of the rectangle by two.
This results in:
4/2
8/2
Now, perform the division to find your final answer.
This gives you 2 ft by 4 ft.
Answer choice C is the best option.
I hope this helps! :)
