We simply rearrange the equation to find t:
rt = d
t = d/r
You would spend about 46.3 hours driving
Step-by-step explanation:
To drive from New York City, to Los Angeles,
- You must drive about 2,779 miles
- You drive 60 miles per hour
We need to find about how many hours you would spend driving
∵ The distance you must drive = 2,779 miles
∵ You drive 60 miles per hour
∵ Distance = speed × time
- Substitute the distance and speed in the rule above
∴ 2,779 = 60 × time
- Divide the two sides by 60
∴ 46.32 = time
∴ The time is about 46.3 hours
You would spend about 46.3 hours driving

Hello!
You can substitute y into the other equation
7 = -3x - 2
Add 2 to both sides
9 = -3x
Divide both sides by -3
-3 = x
The answer is -3
Hope this helps!
Using translation concepts, it is found that the transformation is a reflection over the y-axis.
<h3>What is a translation?</h3>
A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.
For this problem, we have that A is mapped to C and vice-versa. Since they are equidistant to the y-axis, we have that the rule is given by:
(x,y) -> (-x,y).
Meaning that the transformation is a reflection over the y-axis.
For O and B, the rules are given as follows:
- O: (0,0) -> (-0,0) = (0,0).
- B: (0,4) -> (-0, 4) = (0,4).
Showing that points O and B are invariant, keeping the same coordinates and confirming that the transformation is a reflection over the y-axis.
