Answer:
Yea.. Its C
Step-by-step explanation:
So y=mx+b
m=slope
y=-3x+b
subsitutue 1 for x and 4 for y
4=-3(1)+b
4=-3+b
add 3 to both sides
7=b
the equaiton is y=-3x+7
Answer:

Step-by-step explanation:

We want to isolate the x.


Now, we want the x not to have a coefficient. We want it just to be x =. We will do this via inverse operations. Since 3 x is 3 multiplied by x, we will divide each side by 3.

Given :
Xinran walks 3 mi/h uphill, 4 mi/h on flat land and 5 mi/h downhill.
To Find :
If he walks one mile uphill, then one mile on flat land and then returns by the same route to his starting point, how many minutes does he walk.
Solution :
Time taken to walk one mile uphill is :

Time taken to walk two mile on flat land( one on going and one or returning ) is :

Time taken to walk one mile downhill is :

Total time taken :

Therefore, time taken un 62 minutes.
Answer:
12
Step-by-step explanation:
It looks like you're given the equations ...
6px^3 = 3x^6p
Dividing both sides by 3px^3, we get ...
2 = x^3
Substituting that into the left side of the equation, we have ...
6px^3 = 12p
It appears this is the expression you want on the right.
6px^3 = 3x^6p = 12p
