The answer is 84 3/8 because 672 and the left over 3 so it would be 84 3/8.
Hope I Helped!!!!!!!!

Y=Mx +b
B is 0 because that’s where the graph intercepts the y axis.
M is found by picking any two points and finding the rise and run because m is equal rise/run
Points of choice: (-2,4) and (2,-4)
=2−1/2−1 = -8/4
m is equal -2
Y= -2X
Look at the picture below to differentiate between positive and negative slopes.
Well as it looks like to me the cords of the a,b,c are 2,3,1
Answer:
f^-1 (x) = x/5
Step-by-step explanation:
f(x) = 5x
Replace f(x) with y
y= 5x
Exchange x and y
x = 5y
Solve for y
Divide each side by 5
x/5 = 5y/5
x/5 = y
The inverse is x/5
Answer: He travels 280 miles.
Step-by-step explanation:
Speed = Distance / Time
Distance = speed x time
Distance covered at first 2 hours at 55 mph
= distance = 55 X 2= 101 miles
Distance covered in next hour at 70mph
Distance = 70 x 1= 70 miles
Distance covered in the last 2 hours at 50mph
Distance = 50 x 2= 100 miles
Total distance traveled = 110+70+ 100= 280 miles.
