The correct answer for this question would be option D. Translation 4 units up. The figure that shows <span>a reflection of pre-image QRS over the line t is translation 4 units up. The explanation for this is that, when an image reflect across the line, it's become the mirror image but not totally necessary that it is the same. And if you move the figure 4 units up, it will be on top of it. Hope this answer helps.</span>

Answer:

h = 13.333 +693.333/r

Step-by-step explanation:

For h hours, Brandee's pay will be ...

pay = 40r +(h -40)(1.5r) . . . . 40 hours at rate r + overtime (h-40) hours at 1.5r

pay = 40r +1.5hr -60r . . . . . eliminate parentheses

pay = 1.5hr -20r . . . . . . . . . . collect terms

Solving for h, we have ...

pay +20r = 1.5hr . . . . . . . . . . add 20r

h = (pay +20r)/(1.5r) . . . . . . . . divide by 1.5r

For the given pay of 800 +240 = 1040, we have ...

h = (1040 +20r)/(1.5r)

h = 13.333 +693.333/r . . . . . simplify to 2 terms

<em>Additional comments</em>

You need to know r to find the number of hours Brandee worked. She got paid $800 for a presumed 40-hours of regular time, so made r = $20 per hour. The above formula will tell you she worked 48 hours in the pay period.
