No, because x-6 is an expression: it is not an inequality.

-4x + 2 = 6 -4x = 6 - 2 -4x = 4 x = 4 / -4 x = -1

-8

6

A number is called a "solution" for an inequality if, when you plug that number into the variable, the inequality becomes true. For example, 4 is a solution to the inequality "x + 5 < 10", because when you plug in 4 for x, you get "4 + 5 < 10", which is true. (4 plus 5 is 9, which is less than 10.) On the other hand, 6 is not a solution to the inequality "x + 5 < 10", because when you plug in 6 for x, you get "6 + 5 < 10", which is false. (6 plus 5 is 11, which isn't less than 10.)

6, 5, 4

No, it is an expression.

That already IS the inequality.

x ∉ {-6, 6}

4 & |-4|

There can be no answer because there is no inequality in the question.

No.

The inequality is: x+2y > 4

Yes

if x2 ≠ 16, then: {x | x ∈ ℜ, x ∉ (4, -4)}

x^4 is not an inequality. (An inequality has a "bigger than or equal to/less than or equal to/less than/bigger than" sign involved. I.e not an "equals" sign, since this would be an "equality"). But x^4 is not an equality, nor an inequality.

-4r+6=14 isn't an inequality, its a linear equation. Anyway... -4r+6=14 (-6) -4r=8 (/4) -r=2 (x-1) r=-2

(X+6)/4 >= 2 First, remove the fraction on the left side by multiplying both sides by four X+6 >= 8 Subtract 6 from both sides to get your X value X >= 2

Through signs of inequality Solve each inequality Graph the solution? 2(m-3)+7<21 4(n-2)-6>18 9(x+2)>9(-3)

heres an example: 3x+4>10 in this case, the answer to this inequality would be x>2

If this is an inequality (6 is less than x, or 6 < x), then x is an integer or other value greater than 6.---The variable statement "6 less than x" is (x - 6)This is a value (variable and constant) where the value of x is determined by an equationsuch as x-6 = 4 (x is positive 2) or y = x-6 (y is 6 less than x).

The inequality sign is neglected due to the omitted punctuation for the question. Assume x + 8 ≤ 14. Then, subtract both sides to get: x ≤ 6. If x + 8 < 14, then x < 6. If x + 8 > 14, then x > 6. If x + 8 ≥ 14, then x ≥ 6.

Yes, taking the reciprocal (raising each side to the -1 power) of each side of a compound inequality can flip the signs of the inequality. This can be useful when you have an inequality with 'x' in the quotient. Taking the reciprocal of each side can be a more direct way of solving the inequality than multiplying each side by 'x'. The following is an example: | 2/x - 2 | < 4 Following the rules for an absolute value inequality we obtain the following compound inequality: -4 < 2/x - 2 < 4 Next add 2 to each side to get 'x' by itself. -2 < 2/x < 6 Here we can multiply each side by 'x' to deal with 'x' in the quotient, but instead we'll raise each side to an exponent of (-1). We obtain the following: -1/2 > x/2 > 1/6 (Notice the signs flip.) We rewrite as: 1/6 < x/2 < -1/2 Next multiply each side by 2 to get 'x' by itself. 1/3 < x < -1 Our solution set is the following: {x: x > 1/3 OR x < -1} Which is the union of the two infinite intervals (-infinity, -1) AND (1/3, infinity). For these types of inequalities if we believe that perhaps we've made a mistake or that our signs are wrong, we can check our work by plugging in some values for x and evaluating the inequality to see whether or not the statement is true. It helps to graph the inequality on a line and by evaluating x at different points on the graph of our inequality for the values of x that make our statement true; we can see exactly what the inequality looks like. For example, we will evaluate the original inequality with points that are less than -1, in between -1 and 1/3, and greater than 1/3. We'll try x = -2 first, |2/(-2) - 2| < 4 |-1-2| < 4 |-3| < 4 -(-3) < 4 3 < 4 True, our solution: x < -1 holds true. Next we'll solve for x = -1/2, |2/(-1/2) - 2| < 4 |-4 - 2| < 4 |-6| < 4 -(-6) < 4 6 < 4 False, this point is not on the graph of our inequality, so we know that the sign of our solution: x < -1 is going in the right direction and holds true. Next we'll solve for x = 1/4, |2/(1/4) -2| < 4 |8 - 2| < 4 |6| < 4 6 < 4 False, this point is not on the graph of our inequality, so it looks like our second solution x > 1/3 is accurate and our sign is most likely going in the correct direction. Lastly, we'll evaluate for a point x > 1/3 and this point should be on the graph of our inequality. |2/(1) - 2| < 4 |2-2| < 4 |0| < 4 0 < 4 True, we've proved that our solution x > 1/3 holds true for the graph of this inequality and that the sign for our solution is going in the correct direction. In fact if we substitute a very large number in for x, say 1,000 we'll notice the left side of our statement gets closer and closer to 2 as x approaches infinity. |2/(1000) -2| < 4 |-1.998| < 4 -(-1.998) < 4 1.998 < 4 True, we know for certain that the solution x > 1/3 holds true for all values of x to infinity. Our solution set again is, {x: x < -1 or x > 1/3} The union of the two infinite intervals is (-infinity, -1) and (1/3, infinity).
