Answer:
Step-by-step explanation:
eq. of line is y-5=1(x+3)
y=x+3+5
y=x+8
I hope this helps you
y=f (x)=x-7
y=x-7
x=y+7
f^-1 (x)=x+7
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! :)
