Answer:
- a) (0,0), (-4, 1), (-1,2)
- b) None
Step-by-step explanation:
- <em>There are two ways of solving similar problems. One- substitute x and y with respective coordinates and verify if the inequalities are correct. Two- graph the lines and see if the points are in the intersection zones.</em>
- <em>We'll go with the first method. </em>
- <em>Remember both inequalities should be correct for the same point to accept it as a solution.</em>
<u>Given points </u>
<h3>a) <u>The system of inequalities</u></h3>
<u>Point (0,0)</u>
- 0 > 0 - 1 = -1 correct
- 0 < -1/2(0) + 2 = 2 - correct
- Yes
<u>Point (-4,1)</u>
- 1 > -4 - 1 = -5 - correct
- 1 < -1/2(-4) + 2 = 4 - correct
- Yes
<u>Point (-1,2)</u>
- 2 > -1 - 1= -2 - correct
- 2 < -1/2(-1) + 2 = 2.5 - correct
- Yes
<h3>b) <u>The system of inequalities</u></h3>
<u>Point (0, 0)</u>
- 0 - 2(0) = 0 ≥ 4 - incorrect
- 2(0) - 0 = 0 ≥ -1 - correct
- No
<u>Point (-4, 1)</u>
- -4 - 2(1) = - 6 ≥ 4 - incorrect
- 2(-4) - 1 = - 9 ≥ -1 - correct
- No
<u>Point (-1,2)</u>
- -1 - 2(2) = -5 ≥ 4 - incorrect
- 2(-1) - 2 = - 4 ≥ -1 - correct
- No
Answer (simplified and mix number):
B. 5/16
C. 6/1 or 6
E. 7/12
F. 7/3 or 2 2/3
To find this, we have to find a value x such that 2*10^9 * x = 4*10^6. This is so that if we find x, 2*10^9 is x times smaller than 4*10^6. Then, using the multiplicative property of equality, we can divide both sides by 2*10^9 (to separate x) to get 4*10^6/2*10^9=x. Since 4/2=2 and 10^6/10^9=1/10^3 (since for every power of 10, we add 1, so we have 10*10*10*10*10*10/(10^6)*(10^3) and the 10^6’s therefore cross out), our answer is 2/10^3=2/1,000. However, this is clearly not the answer we’re looking for, and even if we find out how many times larger 2*10^9 is than 4*10^6 by switching the denominator and numerator, we end up with 500. Thus, you must have entered something wrong.
