The first one we see that the intersection is 3 units to the right and 6 uniits down or x=3 and y=-6 (down=-) so the point is (3,-6)
the solutions (1,2)
we subsitute and find that the answer is the first equation
we add them together and get
we negative the first and add
-2x+2x+y+y=5+5
2y=10
y=10
sutaitute
2x-y=-5
2x-10=-5
we can see that there is 1 solution
Price of each bracelets , P = $5.50 .
Cost price = $0.05 for each of the 21 beads used + $0.74 for each of the two charms used + $1.09 for the chain with clasp used.
Cost price = $( 0.05×21 + 0.74×2 + 1.09 )
Cost price = $3.62 .
Now, profit is given by :
Profit = Selling price - Cost price
Profit = $(5.50 - 3.62)
Profit = $1.88
Therefore, she will not bear any loss.
<span>In order to find the solution, we must solve for 'x' in the initial equation. What we do to one side of the equation to isolate 'x', we must do to the other. If we subtract 5x from both sides were are left with x - 2 = 3. We then add 2 to both sides to completely isolate 'x' and are left with x = 5. This is in the replacement set and is one of the provided solutions, D.</span>
