Answer:
3
Step-by-step explanation:
4.5/3x2=3
or for conforming
7.5/5x2
sry if wrong
Answer:
Solution given:
f(x) =
x-2
let f(x)=y
y =
x-2
interchanging role of x and y
x=
y-2
x+2=
y
y=9(x+2)
y=9x+18
So
<u>F</u><u>-</u><u>¹</u><u>(</u><u>x</u><u>)</u><u>=</u><u>9</u><u>x</u><u>+</u><u>1</u><u>8</u>
<u>a</u><u>n</u><u>d</u>
<u>F</u><u>-</u><u>¹</u><u>(</u><u>-</u><u>1</u><u>)</u><u>=</u><u>9</u><u>*</u><u>-</u><u>1</u><u>+</u><u>1</u><u>8</u><u>=</u><u>-</u><u>9</u><u>+</u><u>1</u><u>8</u><u>=</u><u>9</u>

Answer:
2A /h -b =p
If you need it with a common denominator
(2A -bh)/h = p
Step-by-step explanation:
A = 1/2 ( p+b)h
Multiply each side by 2
2A = ( p+b)h
Divide by h
2A/h = ( p+b)h/h
2A/h = ( p+b)
Subtract b
2A/h -b = p+b -b
2A /h -b =p
If you need it with a common denominator
(2A -bh)/h = p
