Answer:
The inverse function
Step-by-step explanation:
The given function is g(x) = 1/4 x + 5
Let's take g(x) = y
y = 1/4 x + 5
To find the inverse function, change x by y and y by x, we get
x = 1/4 y + 5
Now write the y interms of x.
Subtract 5 from both sides, we get
x - 5 = 1/4 y
Now isolate y.
y = (x - 5) ÷ (1/4)
y = 4(x - 5)
y = 4x - 20
Therefore, the inverse of g(x) is g^(-1) (x) = 4x - 20
Thank you.
A - side of small map
a+6 - side of larger map
(a+6)² - area of larger map
(a+6)² = 121
(a+6)² = 11² |√(...)
a+6 = 11 |-6
a+6-6 = 11-6

Answer:
a)1 : 4 and 5 : 20
Step-by-step explanation:
If a ratio is a proportion that means the
quantity on the left hand side is lesser than the quantity on the right hand side; it's a part of a whole, a small fraction.
Example of proportion ratios:
4 : 7
7 : 29
90 : 200
68 : 140
Example of non-prpotion ratios:
7 : 4
80 : 19
29 : 20
If they're making 75 pies an hour, and working 8 hours a day, you would multiply 8 by 75. 8x75=600. Hope this helps!
Answer:
x = (4r +3)/(r +2)
Step-by-step explanation:
Collect x terms, then divide by the coefficient of x.
x(r +2) = 4r +3
x = (4r +3)/(r +2)
