Answer:
The distance each bus travels is given as d=tr where
- d is distance bus travels
- t is a time bus travels
- r is the speed of the bus
:
Distance first bus travels for 4 hours is d1=4r.
Distance other bus travels for 4 hours is d2=4(r+12).
:
The total distance between them is 480 miles and since they go in opposite directions this distance is the sum of distances each bus travels.
:
d1+d2=480
4r+4(r+12)=480
4r+4r+48=480
8r+48=480
8r=432
r=432/8
r=54 mph, this is a speed of the first bus
:
r+12=66 mph, this is the speed of the second bus
Hope this helps you!!!! :D
Start with your given equation - F=9/5C+32
Subtract 32 from both sides - F-32=(9/5) degrees C
Multiply both sides by 5 - 5(F-32)=9C
Divide both sides by 9 to isolate C - (5/9)(F-32)=C
Answer - C=(5/9)(F-32)

You must convert point slope form to standard form in this problem. point= (h,k)
POINT SLOPE:
y-(-1)=(3/4)(x-2)
y+1=(3/4)x-(3/2)
y= (3/4)x-(5/2)
Answer:
Step-by-step explanation:
- -4*(-2/5 + 3x) =
- -4*(-2/5) - 4*(3x) =
- 8/5 - 12x
Correct choice is D
