Answer:
5.6
Step-by-step explanation:
by dividing
The equation in y = mx+b form is y = -450x+2745
where,
x = number of hours that have passed by
y = distance to destination in miles
The y intercept is 2745 since this is the initial starting y value, aka the starting distance. Therefore b = 2745.
The slope is -450 or -450/1 since for each hour, the distance goes down by 450. You can think of it as
slope = (change in y)/(change in x)
slope = (change in distance)/(change in time)
slope = (-450 miles)/(1 hour)
slope = -450
The correct answer is ( A )

Answer:
x _> 9 I dont have the symbol on my phone so I just put the greater than sign there
Step-by-step explanation:
1. Subtract 3 from both sides
5x > 48 - 3
2. simplofy 48 - 3 to 45
5x > 45
3. Divide both sides by 5
x > 45/5
4. Then simplify 45/5 to 9 which gives us the answer
And again I dont have the sign thats why I used the greater than sign
Multiply (2.6 x 10^-7) by 15 to get
3.9 x 10^-6
