Answer:

-13/3

Step-by-step explanation:

Let f(x)=A

x=f'(A)

x=3(A+5)

A=(x-15)/3

f(x)=(x-15)/3

ff(2)=(2-15)/3

=-13/3

Solve the equation.<br> -9x + 1 = -x + 17

ddd [48]

Answer:

The value of $x$ :

$x = -2$

Step-by-step explanation:

Find the value of $x$ :

$-9x + 1 = -x + 17$

-Add both sides by $x$ :

$-9x + 1 + x = -x + x + 17$

$-8x + 1 = 17$

-Subtract both sides by $1$ :

$-8x + 1 - 1 = 17 - 1$

$-8x = 16$

Divide both sides by $-8$ :

$\frac{-8x}{-8} = \frac{16}{-8}$

$x = -2$

So, the final answer would be $x = -2$ .

The bending of a bean varies directly as its mas. A beam is bent 20mm by a mass 0f 40kg. how much will the beam bend with a mass

Naddik [55]

Answer:

The beam will bend by 50 mm with a mass of 100kg?

Step-by-step explanation:

The first step in solving the problem of direct variation is setting up the relation mathematically.

We can do this as follows:

The bending of the beam varies directly as its mass.

$20 \alpha 40kg$

$\alpha$ here is the symbol representing direct variation. To remove this and replace it with an equality sign, we have to introduce a constant of proportionality, k

$20 = k \times 40$

k = 20 /40 = 0.5

We can now use this to find the distance the beam will bend with a mass of 100kg?

This will be

$Bending = 0.5 \times 100 =50mm$

There fore, the beam will bend by 50 mm with a mass of 100kg?
