The answer should be 50x+10=240
A - 12 = -34
a = -34 + 12
a = -22
Answer:
i dont know im just doing this for the points
Answer:
total change in time when you used 5 clues is 10.
Step-by-step explanation:
if you have 3 free clues, then 5-3 =2
That means you used 2 additional clues. 2 clues means 5*2 min reduced which is 10 mins reduced. The total time you have is x and the total time left is x-10 after you used the two clues.
Does this help?
An inverse function produces points (y,x) for every point (x,y) produced by the parent function. So to find the inverse function, you solve for the independent variable and when done switch the variable labels....
y=x+5 subtract 5 from both sides
y-5=x now switch labels
y=x-5
So if f(x)=x+5
f^-1(x)=x-5
