Answer:
y-4=-2(x-2) and y=-2x+8
Step-by-step explanation:
y=-2x+8 is correct because the slope is correct and the y-intercept is 8 as stated
y-4=-2(x-2) is correct because it uses a point given in the correct way and the slope is also correct
2x+y=8 is also correct because it can be converted to slope intercept form as y=-2x+8
Answer:
14.4 acres for corn (if you need to round, it's 14 acres.)
Step-by-step explanation:
40% = 19.2 acres
20% = 9.6 acres
10% = 4.8 acres
40 + 20 + 10 = 70
100-70 = 30
30% = 14.4 acres
Answer:
Step-by-step explanation:
a^2 - b^2 factors into (a + b)(a - b)
So now you have
(a + b)(a - b)
========== = 12
(a + b)
You are given that a <> b
So a + b cancels with (a + b) on the top.
a - b = 12
Answer:
a. 13; Equation = 2N - 7 = 19
b. 2; 8 - 3N = 2
Step-by-step explanation:
a. 2N - 7 = 19
- 2N - 7 + 7 = 19 + 7
<u>- 2N</u> = <u>26</u> = 13
2 2
b. 8 - 3N = 2
8 - 8 - 3N = 2 - 8
<u>- 3N</u> = <u>-6</u> = 2
-3 -3
i would suggest finding the answer, and then rounding it.
so 0.15 (15%) of 23.77 is 3.5655. So round it to the nearest cent which is 3.56
