Answer: Here is the answer!
Step-by-step explanation:
8a-4a=4a
4a-6a=-2a
-2a-8=2a
-2a+2a=8
0 is not equal to 8
empty
It is 3yd (the Hight) x 4 yard(half the base) = 12yard and that is actually double the size of the single triangle we just measured but add its partner back on its:
12 YARD
Step-by-step explanation:
Part A:
Let be the number of mittens and be the number of scarves. Then we have the inequalities:
<em>This says Nivyana and Ana cannot make more than 30 scarves</em>
<em>This says that</em> <em>Nivyana and Ana have to earn at least $1000.</em>
Part B:
The graph is attached.
Notice that the graphs of the inequalities are solid lines, this just means that the points on these lines included to the solutions of each inequality.
The darker shaded region and the solid lines bounding it, are the solutions to the inequalities because that's where the values common to both inequalities are found.
Part C:
From the graph we get two possible solutions:
15 scarves & 10 mittens
25 scarves & 5 mittens.
These two points lie on the solid lines that bound the darker shaded region<em> (I picked those points to stress that the lines bounding the dark region are also solutions.)</em>
