B) 3+2 is the expression equivalent
Answer:
42:18:30
Step-by-step explanation:
42/7=6
3*6=18
5*6=30
Therefore, 42:18:30
Answer:
The answer is b. But you asked for the thought process so...
Step-by-step explanation:
Let speed of the 1st trip x miles / hr. and speed of the 2nd trip 3x / hr.
We know that
Speed = Distance/Time.
Or, Time = Distance/Speed.
So, the time taken to cover a distance of 50 miles on his first trip = 50/x hr.
And the time taken to cover a distance of 300 miles on his later trip = 300/3x hr.
= 100/x hr.
So we can clearly see that his new time compared with the old time was: twice as much.
Have a great day :)

Answer: y = (1/3)x - 2</h3>
Explanation:
The y intercept is -2 because the line crosses the y axis at this location. So b = -2
The slope is m = 1/3 because we go up 1 and over to the right 3 units. For instance, going from (0,-2) to (3,-1) follows this pattern.
You can use the slope formula for two points like (x1,y1) = (0,-2) and (x2,y2) = (3,-1) to find that m = 1/3
The slope formula is m = (y2-y1)/(x2-x1)
So that's how we go from y = mx+b to y = (1/3)x-2
Answer:
P'(-6, -4)
Step-by-step explanation:
The (x, y) coordinates of the plotted point P are (-2, 2).
Putting those values into the translation formula, you get ...
(x, y) ⇒ (x -4, y -6)
(-2, 2) ⇒ (-2 -4, 2 -6) = (-6, -4)
The coordinates of the translated point P' are ...
P'(-6, -4)
