Answer:

f^-1 (x) = (1 - x)/3.

Step-by-step explanation:

f(x) = -3x + 1

3x = 1 - f(x)

x = (1 - f(x)) / 3

So f^-1 x = (1 - x)/3.

Answer:

5/6

Step-by-step explanation:

Dividing fractions:

Step 1: Rewrite the first fraction as it is.

Step 2: Replace the division sign with a multiplication sign.

Step 3: Flip the second fraction.

Step 4: Multiply the fractions and reduce the product if necessary.

Let's use the rule of dividing fractions on your problem.

Step 1: Rewrite the first fraction as it is.

$\dfrac{5}{8}$

Step 2: Replace the division sign with a multiplication sign.

$\dfrac{5}{8} \times$

Step 3: Flip the second fraction.

$\dfrac{5}{8} \times \dfrac{4}{3}$

Step 4: Multiply the fractions and reduce the product if necessary.

To multiply fractions, multiply the numerators together, and multiply the denominators together.

$\dfrac{5}{8} \times \dfrac{4}{3} = \dfrac{5 \times 4}{8 \times 3} = \dfrac{20}{24}$

We notice that the greatest common factor of 20 and 24 is 4, so we divide both the numerator and denominator by 4 to reduce the fraction.

$= \dfrac{4 \times 5}{4 \times 6} = \dfrac{5}{6}$

What’s the answer??????? Pleaseeeeeeee helppppppppppp

Hello from MrBillDoesMath!

Answer:

Choice A, 18x - 6y = 20

Discussion:

Given line

-9x + 3y = 12 (M)

Choice A:

18x - 6y = 20 => divide both sides by -2

-9x + 3y = -10 (N)

The left hand sides of (M) and (N) are equal implying that right hand sides are equal which further implies 12 = -10. Contradiction! so the system M and N has no solution.

Thank you,

MrB
