Answer:
A) y= 40x+100
B) 
Step-by-step explanation:
To solve this, we can set up an equation using y=mx+b.
'b' is the initial cost, whereas 'm' is the monthly cost. This gives us the equation:
A): y=40x+100.
For part B, we can solve for the inverse by switching the x and y. This gives us:
x= 40y+100
Now, continue simplifying to isolate the 'y' on a side:
x-100=40y
Hey!
What I did was I graphed them or you could set them equal to each other and use logs!
I graphed them and found the intersections. There were 2, but one was negative so I checked for a positive intersection and found one.
The first blank is 7 and the other is 140!
Hope this helps!
Answer:
0
Step-by-step explanation:
To solve this equation, first find out 4y, which equals 16. Then do the full equation, 16-16=0.
