A farmer has decided to divide his land area in half in order to plant soy and corn. Calculate the area of the entire area so he
knows how much soil is needed.
Each bag of soil covers 15 square yards. How many bags should the farmer purchase?
1 bag
2 bags
3 bags
4 bags

Answer and Step-by-step explanation:
1-6
a.
What you can do is plug in 6 and start by doing the first machine first, then the second. If this doesn't work, do the second machine, then the first machine.
<em><u>The order that works is second machine, then first machine.</u></em>
<u>Second Machine:</u>
y = = 36 - 6 = 30
Plug into first machine now.
<u>First Machine:</u>
y =
We see that the result is 5.
b. <em><u>If we were to do the order of second machine, then first machine, we will never get a negative result (or -5 for that matter), due to the fact that you can't algebraically square root a negative number.</u></em>
<em><u>However, if we were to do the order of first machine, second machine, we can get a negative number. To get -5, we plug in 6 for x in the first machine, getting an answer of 1. We plug this into the second machine, getting 1^2 - 6, which results in -5.</u></em>
1-7. The absolute value of a value is the positive version of that value.
a. |54| = <em><u>54</u></em>
b. =
c. |3| - |-1| = 3 - 1 = <em><u>2</u></em>
d. |2.2 - 5.13| = |-2.93| = <em><u>2.93</u></em>

<u>(6 boxes on each side)</u>
b.<em><u> The amount of squares on each side of the figure increases by 1.</u></em>
c. <em><u>There would be 1 square, because we know that the pattern is there is 2 squares added to the next figure, 1 at each end. If we go back a figure, we take away 2 squares.</u></em>
1-9.
a. -42 - 17 = <em><u>-59</u></em>
b. 8 - (-9) = 8 + 9 = <em><u>17</u></em>
c. 8(-9) = <em><u>-72</u></em>
d. -42 ÷ (-7) = <em><u>6</u></em>
e. -2(-3)(-4) = 6(-4) = <em><u>24</u></em>
f. -18 - 7 = <em><u>-25</u></em>
g. = <em><u>25</u></em>
h. = <em><u>-25</u></em>
i. = <em><u>7</u></em>
1-10. x = 2 Plug 2 in for x, then solve.
a. y = 7 - 3(2) = 7 - 6 = <em><u>1</u></em>
b. y = = 4 - 1 = <em><u>3</u></em>
c. y = = <em><u>9</u></em>

<h3>Answer: 24.5 </h3>
============================================================
Explanation:
It might help to draw it out. See the diagram below.
The base is JK which is 7 units long. I'm picking this as the base because this segment is completely horizontal.
Notice how the base JK spans from x = -3 to x = 4, which we can use subtraction and absolute value to get |J-K| = |-3-4| = 7.
The height is always perpendicular to the base. If the base is JK = 7, then the height is the vertical distance from K (or J) to L. This vertical distance is also 7 units. Subtract the y coordinates and apply absolute value. The base and height aren't always the same number.
Now we can find the area of the triangle
area = base*height/2
area = 7*7/2
area = 49/2
area = 24.5 square units
