We need to find the points that are solutions, that is, the points that lie in the shaded region.
Let's try the ordered pair (1,2). This isn't in the shaded region, so it is not a solution of the system.
The same goes for (-10, 10) and (-2,0).
But when you plot (0,10), it does lie in the shaded region, so it's a solution of the system of inequalities.
Does anyone else here know that answer/
Hi so imagine a tent... It looks like a pyramid right?
Well when its asking for a tent flap, its talking about one triangle of the pyramid.
So its asking you to find the area of one triangle of the pyramid.
Does this make sense??
So the formula for an area of a triangle is (b*h)/2
So the answer is multiply the two numbers together then divide by 2.
Does this make sense?
Answer:
He is correct because the key term is "greater than". This indicates that inequalities should be used here. Now, we write the inequality.
Explanation:
Let L = length
Let w = width
Perimeter = 2L + 2w
L = 100
Perimeter > 400
2(100) + 2w > 400
200 + 2w > 400 is the inequality
Subtract 200 on both sides of inequality.
2w > 200
w > 100
The width is at least 100 centimeters.
