Y= mx+b (slope intercept form)
m= the slope (in this case 8)
b= the y-intercept (-3)
the answer: y=8x-3
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
Answer:
You plug in x and solve for each value. Look at attachment for answers
Step-by-step explanation:
Unit vector along the direction v = <3,1,-4> is :
So, unit vector opposing the 
is :
so, vector of magnitude 3 units in opposite direction from v is :
Hence, this is the required solution.
Answer:
2x²y+(x²y-2xy²) = 3x²y-2xy²
(5xy²-x²y) +3x²y = 5xy²-2x²y
4x²y+(x²y+xy²) = 5x²y+xy²
x²y+(-2xy²-4x²y) = -3x²y-2xy²
Step-by-step explanation: there you go
