\dfrac{a}{4}-\dfrac{5}{6}=-\dfrac{1}{2}\qquad\text{multiply both sides by common denominator 12}\\\\12\cdot\dfrac{a}{4}-12\cdot\dfrac{5}{6}=12\cdot\left(-\dfrac{1}{2}\right)\\\\3\cdot a-2\cdot5=6\cdot(-1)\\\\3a-10=-6\qquad\text{add 10 to both sides}\\\\3a=4\qquad\text{divide both sides by 3}\\\\\boxed{a=\dfrac{4}{3}=1\dfrac{1}{3}}

Answer:

a = 4/3

Step-by-step explanation:

a/4 - 5/6 + 5/6 = -1/2 + 5/6

a/4 = 1/3

4a/4 = 1 x 4/3

a = 4/3

HELP PLS BRAINLIEST IF POSSIBBLE<br> factor each polynomial completely a^2-ab-8a+8a brainly
sineoko [7]

Answer:

a(a - b)

Step-by-step explanation:

<u>given </u><u>polynomial</u>:  a²- ab - 8a + 8a

We can first simplify this answer by removing like terms,

- 8a + 8a = 0

so we have a²- ab in. the simplest form

we can take this one step further and factor out the a (not simplest form)

a time a = a²

a times b = ab

hence, a(a - b)

Which table shows a no change linear relationship?
Phantasy [73]

Answer:

C

Step-by-step explanation:

Each of the tables is a linear relationship. Linear relationships increase or decrease steadily by adding or subtracting a constant. Table A increases by 5. Table B decreases by 2. Table C doesn't change. Table D increase by 4.

A "no change" means the y values never change. The constant is 0 and is a horizontal line. Table C is the solution.

Which point is a solution to the system of inequalities below?
vodomira [7]

The ordered pair which is a solution to the given inequality is: C. (2, 1).

<h3>What is an inequality?</h3>

An inequality can be defined as a mathematical relation that compares two (2) or more integers and variables in an equation based on any of the following arguments:

  • Less than (<).
  • Greater than (>).
  • Less than or equal to (≤).
  • Greater than or equal to (≥).

Next, we would test the ordered pair with the given inequality to determine a solution as follows:

For ordered pair (4, 4), we have:

3x + 2y < 15

3(4) + 2(4) < 15

12 + 8 < 15

20 < 15 (False).

For ordered pair (3, 3), we have:

3x + 2y < 15

3(3) + 2(3) < 15

9 + 6 < 15

15 < 15 (False).

7x - 4y > 9

7(3) - 4(3) > 9

21 - 12 > 9

9 > 9 (False)

For ordered pair (2, 1), we have:

3x + 2y < 15

3(2) + 2(1) < 15

6 + 2 < 15

8 < 15 (True).

7x - 4y > 9

7(2) - 4(1) > 9

14 - 4 > 9

10 > 9 (True)

For ordered pair (1, 0), we have:

3x + 2y < 15

3(1) + 2(0) < 15

3 + 0 < 15

3 < 15 (True).

7x - 4y > 9

7(1) - 4(0) > 9

7 - 4 > 9

3 > 9 (False)
