|x|, if x=10; .3; 0; −2.7; −9
alekssr [168]

Answer:

For \left | x \right | we will have positive values only.

\left | -2.7 |\right =2.7

\left | -9 |\right =9

Rest are positive so will give positive values out of the modulus function.

Step-by-step explanation:

The absolute value of any number is its positive value only.

As for example (-2.7) and (2.7) both are having equal distance from 0 in a number line, one on the left other on the right side of the number line but are equidistant from 0.

So absolute value of a number is its distance on number line from reference point 0.

One by one we will work with all of our question.

\left | 10 |\right =10

\left | 0.3 |\right =0.3

\left | 0 |\right =0

\left | -2.7 |\right =2.7

\left | -9 |\right =9

So we have to take the positive number out of the modulus function that is also called absolute value.

Write the quadratic equation in standard form and then choose the value of "b." (2x - 1)(x + 6) = 0
Eddi Din [679]

ANSWER

b=11

EXPLANATION

The given quadratic equation is

(2x - 1)(x + 6) = 0

We expand to get:

2 {x}^{2}  + 12x - x - 6 = 0

We simplify further by combining the x terms.

2 {x}^{2}  + 11x - 6 = 0

This is the standard form.

Comparing to

a{x}^{2}  + bx  + c= 0

We have b=11
