Answer:

X<6

Step-by-step explanation:

x-8<-2

So first off, you want to get X by itself. To do that you have to do the opposite of what the number is. If the number is negative you add it. If the number is positive, you subtract it. What you do on one side, you do on both.

x-8<-2

+8 +8

X<-2+8

Next, You need to add alike terms.

X<6

Answer:

$x>\frac{1}{2} \\x$

Step-by-step explanation:

If we solve for 'x' variable, its recommended to multiply 'x' variable in both sides of inequality:

we have $\frac{1}{4}< x^{2} \\$

This is a quadratic equation, two answer are going to be obtained from here.

since $\sqrt{x^{2} } = |x|$

Applying square roots to both sides of inequality sign we wil have the following

$\sqrt{\frac{1}{4} } < \sqrt{x^{2} }$

This leaves to the following

$\frac{1}{4}$

remember that $|x|= +/ - x$

$x>\frac{1}{2} \\x$

What is the slope of the line that contains the points (3,1) and (2,-3)

Goryan [66]

$\bf (\stackrel{x_1}{3}~,~\stackrel{y_1}{1})\qquad (\stackrel{x_2}{2}~,~\stackrel{y_2}{-3}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-3-1}{2-3}\implies \cfrac{-4}{-1}\implies 4$

High concentrations of carbon monoxide CO can cause coma and possible death. The time required for a person to reach a COHb leve

ale4655 [162]

Answer:

A) 10.38hours

B) 617.95 is the concerntration of CO

Step-by-step explanation:

A) when x=600

T= 0.0002x^2 - 0.316x + 127.9

T= 0.0002(600)^2 -0.316(600) + 127.9

T= 10.38secs

B) to find the concerntration, use Almighty formular

X=-b+-sqrt(b^2-4ac)/2a

0.0002x^2-0.316x-127.9=9

0.0002x^2 - 0.316x + 118.9=0

X= 0.316 +- sqrt(0.316^2) -4(0.0002×118.9)/(2×0.0002)

X= 0.316+(0.68817/0.0004)=962.05 or

X=-0.316 -0.68817/0.0004 =617.95

Therefore X is within the domain of 617.95 is the concerntration
