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.
Answer:
So trapezoid is 1/2(a+b) × h
So 1/2(16)(6)× (12)

Answer:
Length = 502 ft
Width = 212 ft
Step-by-step explanation:
Recall the formula for the perimeter of a rectangle of length "L" and width "W":
Perimeter = 2 L + 2 W = 1428 ft
Now, since the length is 78 ft more than twice the width, then we can write this in mathematical form as:
L = 2 W +78
so, 2 W = L -7 8
and now replace "2 W" with it equivalent "L - 78" in the first perimeter equation and solve for "L":
2 L + L - 78 = 1428
3 L = 1428 + 78
3 L = 1506
L = 1506/3
L = 502 ft
Then the width W can be obtained via:
2 W = L - 78
2 w = 502 -78
2 W = 424
w = 212 ft
