Answer:

Exact Form:

x= −15/8

Decimal Form:

x=− 1.875

Mixed Number Form:

x= -1(7)/(8)

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Is the line for the equation y = −8 horizontal or vertical? What is the slope of this line?

ZanzabumX [31]

Check the picture below.

so, say let's use two points on that line to see what's its slope then.

$\bf (\stackrel{x_1}{-6}~,~\stackrel{y_1}{-8})\qquad (\stackrel{x_2}{4}~,~\stackrel{y_2}{-8}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-8-(-8)}{4-(-6)}\implies \cfrac{-8+8 }{4+6}\implies \cfrac{0}{10}\implies 0$

Which is the simplified form of the expression (6-4)-9

Veseljchak [2.6K]

I'll give you a hint. <u><em>You had to used pemdas stands for: p-parenthesis, e-exponents, m-multiply, d-divide, a-add, and s-subtracting.</em></u>

First you had to calculate with parenthesis first.

$(6-4)=2-9$

Then you add and subtract from left to right.

$2-9=-7$

Final answer $\boxed{=-7}$

Hope this helps!

And thank you for posting your question at here on brainly, and have a great day.

8. A 140-pound female has three mixed drinks one right after the other.

Sonja [21]

The BAC of the female is an illustration of proportion

The BAC after consuming the three drinks is 0.029w
The BAC three hours after consuming the drinks is 0.087 w

<h3>How to calculate the BAC?</h3>

BAC is calculated using:

BAC = Alcohol consumed/(Body Weight * R)

The weight is given as:

Body weight = 140 lb

Convert to kg

Body weight = 63.5 kg

For female

R = 0.55

So, we have:

BAC = Alcohol/(63.5 * 0.55)

BAC = Alcohol/34.925

BAC = 0.029Alcohol

The weight or volume of the alcohol consumed is given.

So, we represent it with w.

BAC = 0.029w

Hence, the BAC after consuming the three drinks is 0.029w

<h3>How to calculate the BAC after 3 hours?</h3>

We have:

BAC1 = 0.029w

Time (t) = 3 hours

The BAC after 3 hours is

BAC = BAC1 * (t - 0.015)

So, we have:

BAC = 0.029w * (3 - 0.015)

Evaluate the product

BAC = 0.087w

Hence, the BAC three hours after consuming the drinks is 0.087 w
