Use a table of signs to solve the inequality
bulgar [2K]

The interval of the provided inequality expression is -5/9 to the infinity [(-5/9),∞) using the table of signs to solve the inequality.

<h3>What is the inequality equation?</h3>

Inequality equation is the equation in which the two expressions are compared with greater than, less than or other inequality signs.

The inequality given in the problem is,

4x + \dfrac{5}{9} - 3x \geq 0

Simplify the equation first by adding the same terms,

4x + \dfrac{5}{9} - 3x \geq 0\\4x - 3x+ \dfrac{5}{9}  \geq 0\\x+ \dfrac{5}{9}  \geq 0\\x\geq-\dfrac{5}{9}

Now in this case, if the value x is ranges from -5/9 to infinity.

Thus, the interval of the provided inequality expression is -5/9 to the infinity [(-5/9),∞) using the table of signs to solve the inequality.

Given the two rectangles below. Find the area of the shaded region.
larisa86 [58]

Answer:

75 units²

Step-by-step explanation:

Bigger rectangle: length * width

                           : 10 * 9

                           : 90 units²

smaller rectangle: length * width

                             : 3 * 5

                             : 15 units²

Shaded region = Bigger rectangle - smaller rectangle

                         =     90 units²      -     15 units²

                         =        75 units²
