I think this is what you are asking for hope it helps: cost=.17M+50
x + (-4) = 10.
We can use the positive - negative rule.
x + (-4) = 10.
x - 4 = 10.
x = 10 + 4
x = 14.
The answer would be 30-10 and if you dove it all the way it would be 20.
Hope this helps.
Answer:
y=1/4x+3
Step-by-step explanation:
To find the inverse, switch x and y or f(x)
f(x)=4x-12
y=4x-12
x=4y-12
Add 12 to both sides
x+12=4y-12+12
x+12=4y
Divide both sides by 4
x+12/4=y
1/4x+12/4=y
1/4x+3=y
y=1/4x+3
