Answer:
Step-by-step explanation:
f-1(x) is the inverse of f(x)
to find the inverse let’s set the equation up like this
y = 4x -2
now we’ll switch x and y
x = 4y -2
and solve for y
x + 2 = 4y
x/4 + 2/4 = y
the inverse is
y = x/4 + 1/2
this equation is written in y = mx + b form
where b = y intercept
so the y intercept is 1/2
12/6 + 2/3 + 3/4
MMC of 6, 3 and 4 is 12
So 24+8+9/12 = 41/12 = 3,41 approximately.
Answer:
y=-7/2x+10
Step-by-step explanation:
7x+2y=20
2y=20-7x
2y=-7x+20
y=-7/2x+20/2
y=-7/2x+10
Answer: Events A and B are independent because P(A/B)=P(A).
