Answer: List of prime numbers before 39: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37.
Step-by-step explanation:
The correct equation for this transformation is given as (x, y) ⇒ (x - 9, -(y + 2))
<h3>What is a
transformation?</h3>
Transformation is the movement of a point from its initial location to a new location. Types of transformation are <em>reflection, translation, rotation and dilation.</em>
Translation is the movement of a point either<em> up, down, left or right</em> on the coordinate plane.
The graph of √(5x - x²) was translated 9 units left and 2 units up, then reflected over the x axis to get the new graph.
The correct equation for this transformation is given as (x, y) ⇒ (x - 9, -(y + 2))

First, we translate the information that the question gives us:20+x is "twenty added to a certain number"(20+x)/5 is "the sum divided by five"1+12x is "one more than twelve times the original number"Putting it all together, we get the following equation:(x+20)/5 = 1 + 12xSolve for x:x+20=5(1+12x)x+20=5+60x20-5=60x-x15=59x15/59 = xTherefore, the original number was 15/59
Speed = distance divided by time. Plug in what you know.
Speed = 51.2 km / 4 hrs. ****** Simplify *******************
Speed = 12.8 km/hr
