Recall your d = rt, distance = rate * time
if say train B has a speed of "r", then A has a speed of "r-14".
now, they each travelled those miles in the same time, say "t" hours.
how fast is Train A? well, r - 14.
Answer:
Step-by-step explanation:
341,611 rounded to the nearest thousand is 342,000
(6 is higher than5)
Using translation concepts, we have that:
- Function f(x) underwent a reflection over the y-axis.
- Function g(x) underwent a reflection over the x-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 function f(x), the multiplication by -1 of the function is in the output, meaning that it was a reflection over the y-axis. For function g(x), the multiplication is in the input, the domain, hence the reflection was over the x-axis.

Answer:
There is no sign you can not figure it out
Step-by-step explanation:
Answer:
x + y + z = 180 (this is the first equation)
w + z = 180 (this is the second equation)
Now, rewrite the second equation as z = 180 - w and substitute that for z in the first equation:
x + y + (180 - w) = 180
x + y - w = 0
x + y = w
