<h3>Answer:  0</h3>

The discriminant is the number under the square root of the quadratic formula

x = \frac{-b\pm\sqrt{b^2-4ac}}{2a}

The discriminant formula is D = b^2-4ac

If D = 0, then the whole square root portion is 0 meaning we end up with the solution x = -\frac{b}{2a}

Shade the model to show the decimal 0.542 using 100 grid and 10 grid
kherson [118]

0.542=0.500 + 0.040+0.002

          = \frac{5}{10} + \frac{4}{100} +\frac{2}{1000}

         =5 tenth + 4 hundredths + two thousandths

One tenth = \frac{1}{10}

One Hundredth= \frac{1}{100}

One thousandth= \frac{1}{1000}

Which graph shows the solution set for Negative 4.4 greater-than-or-equal-to 1.6 x minus 3.6?
____ [38]

Answer:

A number line going from negative 7 to negative 1. A closed circle is at negative 5. Everything to the right of the circle is shaded.

Step-by-step explanation:

-4.4 ≥ 1.6 x - 3.6

Solving for the value of x,

1.6 x ≤ -4.4 + 3.6

 1.6 x ≤ - 0.8

Dividing 1.6 from both sides to know value of x

x ≤ - 0.5
