Answer:
4 hours
Step-by-step explanation:
We want to find at what x value, will y be the same for both companies. To do this, we can set the two expressions equal to each other.
25x+250=50x+150
To solve, we have to get all the variables to one side of the equation, and all the numbers to the other
Subtract 25x from both sides
250=25x+150
Subtract 150 from both sides
100=25x
Now, we have all the variables on one side, and the numbers on the other.
To isolate the variable, divide by 25
x=4
So, at 4 hours,the cost will be the same
Hope this helps! :)
Answer:
y= -50x + 400
Step-by-step explanation:
-50 miles from the place which means they are going further and further away so it is negative. And its 400 because y=mx+b the b is 400 because thats where they started. Also it said it was correct on A-p-e-x.
Answer:
-1/4
1
-1/4
1
Step-by-step explanation:
Slope is obtained thus :
(y2 - y1) / (x2 - x1)
Slope ST :
S(1, 4) ; T(5, 3) ;
x1 = 1, y1 = 4 ; x2 = 5 ; y2 = 3
Slope ST = (3 - 4) / (5 - 1) = - 1 / 4
Slope TU :
T(5, 3) ; U(3, 1)
x1 = 5, y1 = 3 ; x2 = 3 ; y2 = 1
Slope TU = (1 - 3) / (3 - 5) = - 2/ - 2 = 1
Slope UV :
U(3, 1) ; V(-1, 2)
x1 = 3, y1 = 1 ; x2 = - 1 ; y2 = 2
Slope UV = (2 - 1) / (-1 - 3) = 1 /-4 = - 1/4
Slope SV:
S(1, 4) ; V(-1, 2)
x1 = 1, y1 = 4 ; x2 = - 1, y2 = 2
Slope SV = (2 - 4) / (-1 - 1) = - 2 / - 2 = 1
