It has to be C heads- tails -3 I'm not sure it kind makes sense to me
<span>Put it in the form of y =mx +b, or in this instance, y> mx +b
move the (1/2) x to the right by adding it to both sides of the inequality
(1/3)y>(1/2)x +2
Multiply by 3 on both sides to get y by itself.
y>(3/2) x +6
This is a graph with y intercept of (0,6) and a moderate upward and to the right slope. Because it is > , the line on the graph will NOT be part of the solution.
The easiest way to find the side of the graph that the inequality satisfies is to use (0,0) and see if it works or doesn't work. In the original equation, 0-0>2 does NOT work, so the area where the inequality works is to the up and left of the graph, which should be a dotted line to show that the inequality is greater than only.
The point (6,-2) should work.
Test it. 6*(1/3)-(-2)*(1/2)>0 ; 2-(-1)=3, and 3>2 It does work.
The point (6,2) should not work
Test it. 6 *(1/3)-2(1/2)=2-1 ; 1 is NOT >2, so it does not work.
If the graph goes through the origin, then pick a point near the graph with a small x or y.</span>
Step-by-step explanation:
From what you said, i would say that a line segment would be 1/3 od AB since AB is 300%

Answer: B. (3,-2)</h3>
There are two ways to confirm this is the answer. The first is to note that (3,-2) is on the boundary, so it is part of the solution set. This only works if the boundary line is a solid line (as opposed to a dashed or dotted line).
The second way is to plug (x,y) = (3,-2) into the given inequality to find that
which is a true statement. So this confirms that (3,-2) is in the solution set of the inequality.
The appropriate choice is ...
D: Function 1 shows a greater rate of change, because Maddy spends $20 each month and Caitlin spends $18 each month.
_____
Each time the month number in Function 1 goes up by 1, the account balance goes down by $20. Each time the month number in Function 2 goes up by 1, the account balance goes down by $18. Once you have figured out that $20 is more than $18, you know the first two answers cannot be right. The third answer is wrong because Caitlin cannot (and does not) spend -$18 each month.
