2*5
If you want that as an inequality, you write:x <= -10 You can replace "<=" with the corresponding inequality symbol (less than or equal).
In the case of an inequality, if you mulitply by a negative number, you have to reverse the direction of the inequality. E.g.: -x < 10 becomes: x > -10 (Here, I multiplied by -1, and simultaneously reversed the direction of the inequality.)
Flip. You need to reverse the inequality when multiplying or dividing by a negative. -2x < 10 (-1)*(-2x) < (-1)*10 2x > -10 x > -5
heres an example: 3x+4>10 in this case, the answer to this inequality would be x>2
The inequality ( x^2 < 100 ) can be solved by first taking the square root of both sides, giving ( -10 < x < 10 ). Thus, the solution is the interval ( (-10, 10) ). This means that any value of ( x ) within this range will satisfy the inequality.
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.)
2.5 <= 10 x <= b
To clear decimals in an inequality, multiply every term in the inequality by a power of ten that eliminates the decimal points. For example, if the inequality is 0.5x < 1.2, you would multiply all terms by 10 to get 5x < 12. After multiplying, ensure the direction of the inequality remains the same, and proceed to solve the inequality as you normally would.
The inequality that fits this condition is that X is greater than 1.
The inequality (6x + 2y - 10 > 0) can be rewritten in slope-intercept form as (y > -3x + 5). The boundary line is (y = -3x + 5), which has a slope of -3 and a y-intercept of 5. The region above this line represents the solution set for the inequality. Since the inequality is strict (>), the boundary line itself is not included in the solution.
If an inequality states "no more than," you would use the less than or equal to sign (≤). This indicates that the value can be either less than or equal to a specified number. For example, if the inequality is expressing that a variable ( x ) is no more than 10, it would be written as ( x ≤ 10 ).
