how do you have a reflection in the x axis, if the shape is already partially in the third and second quadrent of the graph
IgorLugansk [536]

Its a reflection over an x-axis, whats "positive" goes "negative" and whats "negative" goes "positive" with respect to y.

If a shape S is a subset (made of P_2\cup P_3 of quadrants Q_2,Q_3 then the part P_2 that lies in the second quadrant gets mapped to Q_3 and part P_3 that lies in third quadrant gets mapped to Q_2

Hope this helps.

Please help!!! I will give brainliest but only if you try and help.
Slav-nsk [51]

Answer:

<h2>____</h2><h3>1260 </h3><h2>____</h2>

Since we have to predict, we can use ratios to help us solve this.

12 said yes out of 72 randomly chosen, SO,

if 210 would say yes (goes to play), how many is total??

12 is to 72 AS 210 is to HOW MUCH (let it be x)??

We can setup ratio, cross multiply, and solve for x:

= 12/72= 210/x

= 12x = 210*72

=12x = 15,120

=x = 15,120/12

<h2>=x =1260</h2>
