Hmm, it looks like it could be commutative property of multiplication.
The order of the expression is different.
4(2+3)=
4(5)=20
(2+3)4=
(5)4= 20
You would add up the percentages first, which would bring everything up to 35%. You would then take the original cost of the item, which is $30 and multiple it by the 35%.
The equation would look like...
30 x .35 =
This will give you $10.50, which isn't the final answer.
You would then subtract 10.50 from the $30 that was asked for at the beginning by the retailer.
Your final answer is $19.50. :) Which isn't a bad deal if I say so myself.
Hi!
<u>Positive</u> <u>discriminants</u> will give you <u><em>two</em></u> <u>solutions</u>.
<u>Discriminants</u> <u>equal</u> <u>to</u> <u>zero</u> will give you <u><em>one</em></u> <u>solution</u>.
<u>Negative</u> <u>discriminants</u> will give you <u><em>no</em></u> <u>solutions</u>.
In a graph, the number of solutions is where the graph crosses the x-axis.
In the first graph, we can see it intersects the graph at two points: (2, 0) and (6, 0). Since there are two solutions it is a positive discriminant.
In the second graph, we can see it intersects at one point: the origin, or (0, 0). Since there is one solution it is a discriminant equal to zero.
In the third graph, we can see it doesn't intersect; it is above the x-axis. Since there are no solutions it is a negative discriminant.

I think the answer is B I got this right but it was for a completed grade so i’m not sure
0.03448275862I would round this to the nearest 10th which is 0.035 Or if it is easier you can leave it like it is. :)<span>
