Solve x2 - 8x - 9 = 0. Rewrite the equation so that it is of the form x2 + bx = c.

barxatty [35]

Answer:

x=9,-1 and $x^2+(-8)x=9$

Explanation:

we have been given with the quadratic equation $x^2-8x-9$

we compare the given quadratic equation with general quadratic equation

general quadratic is $ax^2+bx+c=0$

from given quadratic equation a=1,b= -8,c= -9

substituting these values in the formula for discriminant $D=b^{2}-4ac$

$D=(-8)^2-4(1)(-9)=100$

Now, to find the value of x

Formula is $x=\frac{-b\pm\sqrt{D}}{2a}$

Now, substituting the values we will get

$x=\frac{-(-8)\pm\sqrt{100}} {2}= \frac{8\pm10}{2}=9,-1$

And rewritting the given equation by shifting 9 to right hand side of the given equation and taking minus inside the bracket so as to convert it in the form of

$x^2+bx=c$

Solve the following inequality: -20 < 4 - 2x A. 8 >x B. 8 C. 12 > x D. 12

Mama L [17]

Answer:

-20 < 4 - 2x (subtract 4 from both sides)

-24 < -2x (divide each side by -2)

12> x (when you divide by a negative number, the inequality flips)

x< 12 ( I always put it so x is first)

so the answer is C

The table below shows the typical hours worked by employees at a company. A new employee is offered an annual salary of $37,000.

Mademuasel [1]

Answer:

Salaried pay is preferable for a new employee

Step-by-step explanation:

As per table, hours worked per week:

0+ 8.5+ 9.5+ 7.5+ 8+ 8.5+ 4 = 46

Employee gets paid for 46 hours per week:

$40*14 + (46- 40)*$21 = $686

Average yearly salary would be:

$686/7*365 = $35770

Comparing with annual salary, we see:

$37000 > $35770

As we see, hourly employees get paid less, so the new employee should choose annual salary option
