Answer:
7
Step-by-step explanation:
He has a 1/6 chance of rolling a 6
1/6 of 42 = 7
Answer:
y = -3x - 31
Step-by-step explanation:
We know that the slope intercept formula of a line is;
y = mx + c
From the given equation of y = -3x + 2, we can say that the slope is -3.
Now, parallel lines have the same slope.
Thus, for passing through (-8,-7), the slope will be -3.
So, equation is;
(y - y1) = m(x - x1)
Thus;
(y - (-7)) = -3(x - (-8))
y + 7 = -3(x + 8)
y = -3x - 24 - 7
y = -3x - 31
The easiest way to find an inverse of a function is to substitute the original function's x with y.
y=1/(x-4)-6 ---- original equation
x=1/(y-4)-6 ---- inverted
Now we just need to isolate y again, with a little bit of manipulation this is easy
x+6=1/(y-4)
(x+6)(y-4)=1
y-4=1/(x+6)
y=1/(x+6)+4
We could see that x cannot be -6 since you cannot divide by 0
Therefore the answer to this problem is A
f-1(x)=1/(x+6)+4 where x =/= -6
Hope it helped!!!!
