Answer:

Step-by-step explanation:

As given, we have here, an original equation: f(x) = 3x + 2.

To work out f(a - 4), we substitute x = a - 4 into original equation.

f(a - 4) = 3(a - 4) + 2

We apply the distributive property to keep going.

f(a - 4) = 3a - 3*4 + 2

We perform the multiplication of 3 and 4.

f(a - 4) = 3a - 12 + 2

We perform the addition of (-12) and 2 to finalize the answer.

f(a - 4) = 3a - 10

This is the final answer

I hope this helps!

Find the value of x if a linear function goes through the following points and has the following slope: (x,2), (-4,6), m=3

Anastasy [175]

The slope is defined as

$m=\dfrac{\Delta y}{\Delta x}=\dfrac{6-2}{-4-x}$

So, we have the follwing equation:

$\dfrac{6-2}{-4-x} = 3 \iff 4 = 3(-4-x) \\\iff 4=-12-3x \iff16=-3x \iff x = -\dfrac{16}{3}$

16x² +8-7x-3x2 - 13x

liq [111]

Answer:

$13x^{2}$ -20x+8

Step-by-step explanation:

Step 1: rearrange the equation

16x^2 - 3x^2 - 7x - 13x +8

Step 2: solve the equation

16x^2 - 3x^2 = 13x^2

-7x - 13x = -20x

(the +8 will stay the same)

so when we put it all together it gives us

13x^2 - 20x + 8

There are three dials on a combination lock. Each dial can be set to one of the numbers 1, 2, 3, 4, 5 The three digit number 553

Anika [276]

The number of different three-digit numbers that can be set for the combination lock is 125

<h3>How to determine the number of different locks?</h3>

The digits are given as

Digit = 1, 2, 3, 4, 5

Each digit can be repeated on the number lock.

So, the individual digit of the lock can be any of the 5 digits.

So, we have:

Locks = 5 * 5 * 5

Evaluate

Locks = 125

Hence, the number of different three-digit numbers that can be set for the combination lock is 125
