If ab= 7x-6 and bc= 12-2x. Then what does ac equal?

Ab = (7x-6) →   b = (7x-6)/a   (1)

bc = (12-2x) → b = (12-2x)/c   (2)

Since (1) = (2) → (7x-6)/a = (12-2x)/c OR  a/c = (7x-6)/(12-2x)  (3)

Multiply  both numerators of (3) by the SQUARE of their  respective denominators;

(a*c²)/c = (7x-6)(12-2x)²/(12-2x)
Now simplify:

ac = (7x-6)(12x-2x)  or ac = -14x² + 96x - 72

1 - For this one I am not too sure as I generally only work with values that require an unknown. This one is an unknown asking for the values to see the fraction equivalent to 3/4 however if I had to guess here it would probably be 9/12 as it asks what is equal to 3/4. 3 goes into 9 3 times and into 12 4 times so it equals 3/4. Note: 9/12 has a numerator less than the denom but so does 6/8 which is the lesser fraction and still equals 3/4.
2 - Well simply put. \frac{5}{15} =  \frac{1}{3} 
3 - For this one we have to do a bit of work.
Basically just make an equation such as n for numerator and d for denominator.
d = 2n - 4
Now all we have to do is plug in.
2 * 3 - 4 = 2 
<span>2 * 6 - 4 = 8 </span>
<span>2 * 9 - 4 = 14 </span>
<span>2 * 12 - 4 = 20 
</span>So now we know our numerator or n equals 12.
The denominator or d equals 20 so we would get the fraction of....

The table below shows some inputs and outputs of the invertible function f with domain all real numbers.
Naddik [55]

by the inverse function definition, we will have that:

  • f⁻¹(-2) = 3
  • f⁻¹(1) = 0

<h3>How to find the values of the inverse function?</h3>

Remember that, by definition, for an invertible function f(x) we have that:

f(x) = y

then:

f⁻¹(y) = x

Where f⁻¹(x) is the inverse function of f(x).

Now, we want to find:

f⁻¹(-2)  and f⁻¹(1)

If you look at the given table, we can see that we have the points (3, -2) and (0, 1), which means that:

f(3)= -2

f(0) = 1

Then, by the inverse function definition, we will have that:

  • f⁻¹(-2) = 3
  • f⁻¹(1) = 0

8x - 6x + 1 = 11<br>Please explain your work!<br>Thank you!​
Vesnalui [34]

Answer:

x = 5

Step-by-step explanation:

8x - 6x + 1 = 11

Add 6x to each side (because the 6 is negative)

8x + 1 = 11 - 6x

Subtract 1 from each side (because the 1 is positive)

8x = 10 - 6x

Subtract 6x from 8x

2x = 10

Divide by 2

x = 5
