Let's actually find the sol'n set.
<span>Line A: 2x + 2y = 8
Line B: x + y = 4
becomes
</span><span> 2x + 2y = 8
x + y = 4
------------------ Multiply the 2nd equation by -2, obtaining -2x - 2y = -8,
and then add your result to the first equation:
</span> 2x + 2y = 8
-2x - 2y = -8
------------------- Combine all 3 columns.
0 + 0 = 0
0 always = 0, so there are infinitely many solutions to this system.
200 + [0.15 * (2,500-1,000)] = ?
Answer:
Perimeter: 30
Step-by-step explanation:
So we know that to get the area we multiply the height by the width and we already know the area and height.
Area: 50
Height: 5
So to find the width, we just divide:
50/5 = 10
So now we have everything we need to find the perimeter. The perimeter is all the sides added up. So, 5+10+5+10 = 15+15 = 30
Hope this helps
Answer:
$125
Step-by-step explanation:
To solve this, we need to find 2.5% of 5,000. To do this, we multiply 5,000 by .025. This gets us 125. That means you earn $125 worth of interest in one year.
