Please help!! How can I use the values of the discriminant to describe the solutions?

I think you are referring to the (square root of b^2 - 4ac) in the quadratic formula.
When b^2 - 4ac is less than zero, the solutions to the quadratic equation will be complex (iamginary).

Alejandro uses the steps below to convert StartFraction 5 over 8 EndFraction to a percent. Five-eighths right arrow 8. 0 divided
adoni [48]

Alejandro makes an error in the first steps he divides 8 by 5 which is incorrect he has to divide 5 by 8, and in the second step, he does not multiply the term by 100 and it can be determined by using fraction or percentage.

<h2>Given that,</h2>

Alejandro uses the steps below to convert 5/8 to a percent.

8 divided by 5 = 1.6.,

1.6 = 160 percent

<h3>We have to determine,</h3>

Which best explains Alejandro's error?

<h3>According to the question,</h3>

Alejandro uses the steps below to convert 5/8 to a percent.

8 divided by 5 = 1.6.,

1.6 = 160 percent

The division was computed incorrectly.

The division was completed in the incorrect order. The decimal was moved to the right too many times.

The decimal was moved to the right instead of the left.

Alejandro uses the steps below to convert 5/8 to a percent.

To convert 5/8 into percentages following all the steps given below.

  • Step1; Firstly 5 is divided by 8,

                   = \dfrac{5}{8} \\\\ = 0.625

  • Step2; To convert 0.625 into percentage multiplied by 100,

                    \rm = 0.625 \times 100\\\\= 62.5 \ percent

Hence, Alejandro makes an error in the first steps he divides 8 by 5 which is incorrect he has to divide 5 by 8, and in the second step, he does not multiply the term by 100.

HELPPPPP PLEASEEEE!!!!!! Just number 9

\text{Hey there!}

\text{Equation for company \#1: \$42 + \$0.05x}

\text{Equation for company \#2 \$ 0.08}

\text{Now, let's solve for your equations, shall we?}

\text{First set the overall equation up.}

\text{42 + 0.05x = 0.08x}

\text{Which is reverse back to: 0.08x - 0.05x = 42}

\text{0.08x - 0.05x = 0.03x}

\text{New equation (for now) 0.03x = 42}

\text{Divide each term by 0.03}

\dfrac{\text{0.03x}}{0.03}=\dfrac{42}{0.03}

\text{Cancel out:\ } \dfrac{\text{0.03}}{0.03}\text{ because it equals 1}

\text{Keep:\ }\dfrac{42}{0.03}\text{ because it helps us solve for our answer!}

\dfrac{42}{0.03} = 42\div0.03 \rightarrow 1,400

\text{Total: 1,400 pgs. (pages)}

\boxed{\boxed{\text{\bf{Answer should be:1,400 pages}}}}\checkmark

\text{Good luck on your assignment and enjoy your day!}
