Answer:

Step-by-step explanation:

Distributive property

\frac{-3}{4}*\frac{2}{3}+\frac{3}{4}*\frac{-5}{6}\\\\=\frac{-3}{4}*[\frac{2}{3}+\frac{5}{6}]\\\\=\frac{-3}{4}*[\frac{2*2}{3*2}+\frac{5}{6}]\\\\=\frac{-3}{4}*[\frac{4}{6}+\frac{5}{6}]\\\\=\frac{-3}{4}*[\frac{4+5}{6}]\\\\=\frac{-3}{4}*\frac{9}{6}\\\\=\frac{-1}{4}*\frac{9}{2}\\=\frac{-9}{8}}\\\\=-1\frac{1}{8}

Answer: The answer is -1/8

Step-by-step explanation:

3/4*2/3+3/4*-5/6

3 is cancelled out with 3, 4 with 2, 3 with 6

1/2-5/8

take the L.C.M

4(1)-1(5)/8

4-5/8

=-1/8

Find an equation for the inverse for each of the following.
IgorLugansk [536]

Answer:

  • <em>To solve these first swap x and y, solve for y and name it inverse function</em>

3. <u>y = -8x + 2</u>

  • x = -8y + 2
  • 8y = -x + 2
  • y = -x/8 + 2/8
  • y = -(18)x + 1/4

f⁻¹(x) = -(18)x + 1/4

-----------------------------------------

4.<u> y = (2/3)x - 5</u>

  • x = (2/3)y - 5
  • (2/3)y = x + 5
  • y = (3/2)x + (3/2)5
  • y = 1.5x + 7.5

f⁻¹(x) = 1.5x + 7.5

-----------------------------------------

5. <u>f(x) = 2x² - 6</u>

  • x = 2y² - 6
  • 2y² = x + 6
  • y² = 1/2x + 3
  • y = \sqrt{1/2x + 3}

f⁻¹(x) = \sqrt{1/2x + 3}

-----------------------------------------

6. <u>y = (x - 3)²</u>

  • x = (y - 3)²
  • \sqrt{x} = y - 3
  • y = 3 + \sqrt{x}

f⁻¹(x) = 3 +  \sqrt{x}

Solve the equation 1/2(16x – 6) = 2.
Lorico [155]

Answer:

x = 0.625 or 5/8

Step-by-step explanation:

1/2(16x-6) = 2

8x - 3 = 3

8x = 3 + 3

8x/8 = 9/8

x = 0.625

Pls help me with this answer choice question! brainliest, rattings, thanks etc.
galina1969 [7]

Answer:

graph B

Step-by-step explanation:

Given

3y - 5x < - 6

Since the inequality is < then the line must be broken

If ≤ then line would be solid

The only possible graphs are B and D

Choose a test point in the shaded region of each graph and check validity

graph B (2, 0) ← substitute into left side of inequality

0 - 5(2) = 0 - 10 = - 10 < - 6 ← this is valid

graph D (0, 0 ) ← substitute into left side of inequality

0 - 0 = 0 > - 6 ← this is not valid

Hence graph B is the correct graph

What is the theoretical probability of rolling two consecutive numbers<br>when rolling two dice?​
Art [367]

Answer:

2.7%

Step-by-step explanation:

The probability of rolling the number once is \frac{1}{6}, and the probability of it happening again is \frac{1}{6}, so multiply and get \frac{1}{36}, which is approximately 2.7%
