Remember
if f(x)=y then f⁻¹(y)=x
so since f⁻¹(3)=5, f(5)=3, a point is (5,3)
x intercept is 6
so another point is (6,0)
so
the slope between (5,3) and (6,0) is (0-3)/(6-5)=-3/1=-3
ok, so when x=6, y=0
0=-3(6)+b
0=-18+b
18=b
y=-3x+18 is equation
or
f(x)=-3x+18
We know that
circumference=pi*D
where D is the diameter
diameter=4 ft
circumference=4*pi ft
if one revolution is -------------> 4*pi ft
1320 rev-------------> x
x=1320*4*pi-----> x=5280*pi ft/hout
convert ft to miles
1 mile-----------> 5280 ft
so
5280*pi ft----------> is pi mile
5280*pi ft/hour------> is equal to pi mile/hour
the answer is the option
<span>a. pi</span>
Answer:
567+(6673)- 718)+ 012
Step-by-step explanation:
Given:
The equation is
To find:
The formula where x is the subject of the given formula.
Solution:
To make x the subject of the formula, we need to isolate the variable x.
We have,
Subtracting p from both sides, we get
Therefore, the required formula of x is .
Answer:
x(6+7x)
