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

Step-by-step explanation:
solve the equation for x by finding a,b, and c of the quadratic then applying the quadratic formula (the full thing under "answer:" is the exact answer
Answer:
EH = 9
FH = 7
EG = 6
EF = EH - FH
EF = 9 -7
EF = 2
FG = EG -EF
FG = 6 -2
FG = 4

Answer:
$13,500.
Step-by-step explanation:
Let x represent money spent on monthly bills.
We have been given that last month a museum received €21000 in donations. The ratio of bills to donations was 5:14.
We will use proportions to solve our given problem.




Now, we will subtract $7500 from donations to find the amount spent on new exhibitions as:

Therefore, they spent $13,500 on new exhibitions.
