If f(x) = 5x, what is f–1(x)?

1 answer:

7 0

We are given f(x) = 5x
and we are to find inverse of f(x).

Step 1:
Replace f(x) by y.
So,

y = 5x

Step 2:
Isolate x
So,

x = y/5

Step 3:
Replace x by f'(y)
So,

f'(y) = y/5

Step 4:
Replace all occurrences of y by x.
So,

f'(x) = x/5

Therefore, the inverse of f(x) = 5x is f'(x) = x/5

Answer:

The length of BC is 17 units

Step-by-step explanation:

we know that

An isosceles triangle has two equal sides and two equal angles

In this problem we have an isosceles triangle

Because

m∠ACB=m∠ABC ----> given problem

AC=AB

substitute the given values

$x+9=2x-8$

solve for x

$2x-x=9+8$

$x=17$

therefore

The length of BC is 17 units

What is the slope of the line whose equation is 5y + 6x - 2 = 0

koban [17]

All you need to do to find the slope here is put it into y = mx + b format.

5y + 6x - 2 = 0

the goal is to get the y alone, so...

5y = 2 - 6x

divide both sides by 5

y = 2/5 - (6/5)x

then, just to be clearer for y = mx + b ...... y = (-6/5)x + (2/5)

the slope should be (-6/5)
