Help me answer this question plz

Step-by-step explanation:

The lengths of DF and HI

Step-by-step explanation:

SSS

This means Side Side Side

So to prove this triangle is similar we have to use only true information about the sides.

We can already cross off the second and last answer choices because they are talking about angles.

The first answer choice is about the sides but first we have to determine if its true or not.

Side DF is on the left opposite of angle G

HI is also on the left, opposite of angle I

We can assume those sides are the same but to really know we can check if the other sides match up

We know this constriction has a scale factor of: 1.66666667

If you divide 3.5 by our scale factor you get 2.1

If you divide 5 by our scale factor you get 3

This proves that DG and HJ and FG and IJ would be the matching constricted side

This means that DF and HI would be matching as well making the first answer choice correct.

I hope this helps, don't be afraid to reach out with any further questions! Have a nice day!

step-by-step explanation:

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week

so, we get point as (200,10)

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

now, we can use point slope form of line

now, we can plug values

we can use point

and find b

now, we can plug it back

and we get

now, we can find revenue

we know that

revenue = price*quantity

so, we get
