On a coordinate grid, point p is at (2, 1) and point r is at (−6, −5). points q and s are a reflection of both points across the x-axis. what are the coordinates of q and s?

Q(2, −1), S(−6, 5)

Step-by-step explanation:

The original ordered pairs were  (2, 1) and (−6, −5). When you reflect across the x-axis the x-coordinates of the two ordered pairs are the same, and the y coordinate is the opposite in sign (positive and negative).

so since the original ordered pairs were  (2, 1) and (−6, −5), the reflected ordered pairs would be  Q(2, −1), S(−6, 5) because the y-coordinates are different and the x-coordinates are the same.

Hope this helped fellow FLVS student!!

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°

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
