Step-by-step explanation:
Let f(x)=y
y=2x/X-5
y(x-5)=2x
xy-5y=2x
x(y-2)=5y
x=5y/y-2
Apply x=5y/y-2, on f(x)
f(5y/y-2)=2(5y/y-2)/[(5y/y-2)-5]
=(10y/y-2)/[(5y-5y+10)/y-2]
=10y/10
=y
So f^-1(x)=5y/y-2
Trapezoid: b1 =3m; b2 = 4m
A= 7m 2 What the next missing dimension?
9514 1404 393
Answer:
h = 2m
Step-by-step explanation:
We can put the given values into the area formula and solve for the missing one.
A = (1/2)(b1 +b2)h
7m²= (1/2)(3m +4m)h
7m² = (7/2)m·h
(7m²)(2/(7m)) = h = 2m
The missing height is 2 m.

9514 1404 393
Answer:
-24
Step-by-step explanation:
We can simplify this to ...
b^2 +3(b -b^2) -2a
= b^2 +3b -3b^2 -2a
= -2b^2 +3b -2a . . . . . . . simplified form
This can be made easier for evaluation by factoring out b.
= (-2b +3)b -2a
Using the given values, this is
= (-2(4) +3)(4) -2(2)
= (-5)(4) -4
= -24 . . . . value of the expression

15.it will take 88 minutes to add 16 seats.
It will take 104.5 minutes to add 19 seats.
Step-by-step explanation:
Let m represent number of minutes.
We have been given that an assembly line worker at Rob's Bicycle factory adds a seat to a bicycle to a rate of 2 seats in 11 minutes.
We will use proportions to solve our given problem.
To find the time taken to add 16 seats, we will in our proportion as:
Therefore, it will take 88 minutes to add 16 seats.
To find the time taken to add 19 seats, we will in our proportion as:
Therefore, it will take 104.5 minutes to add 19 seats

3y2-8y2+5y-7+10
-5y2+5y+17
what solution is -5m=8m-2
Answer:
m=2/13
Step-by-step explanation:
Given function:
-5m=8m-2Subtract middle value from both side:
[tex]-5m-8m=8m-2-8m[/tex]Combine like terms:
[tex]-13m=-2[/tex]Divide both sides by the same term:
[tex]\frac{-13}{13}=\frac{-2}{-13}[/tex]Divide the terms:
[tex]=\frac{2}{13}[/tex]Therefore, m=2/13.

Is y = 5(1.04)* A. growth or B. decay?
Answer:
growth
Step-by-step explanation:
Answer:
A. Growth
Step-by-step explanation:
There is a 1 in front of 0.04, which also means 104%, so it's an increase, therefore growth. Decay would be below 100%.
