to graph a LINEar equation, since it's just a straight line, recall, to draw a straight line all you need is two points.

so we can just pick two random "x" values, hmmmmm say x = 0, what's "y"?

y = 7(0)-7 => y = -7....................................... so that gives us the point (0, -7)

hmmm x = 2, what is "y"?

y = 7(2) - 7 => y = 14-7 => y = 7................. so we get the point (2, 7).

then just plot those, and run a line through them.

Answer:

55 hours 13 min

55.2166 hours

Step-by-step explanation:

mon - 3 hr 28 min + 3 hr 49 min = 6 hr 77 min --> 7 hr 17 min

tues -  4 hr 22 min + 4 hr 26 min = 8 hr 48 min

wed- 3 hr 39 min + 4 hr 49 min = 7 hr 88 min -->8 hr 28 min

thurs- 9 hr 51 min + 5 hr 30 min = 14 hr 81 min --> 15 hr 21 min

fri- 9 hr 46 min + 5 hr 33 min = 14 hr 79 min --> 15 hr 19 min

total --> 53 hours 133 min

(-2x²y)³ / (xy²z)² * (-yz)² Hello guys, im having trouble with this babe...
Masja [62]
\frac{(-2x^2y)^3}{(xy^2z)^2(-yz)^2}

On top: (-2)³ = -2 × -2 × -2 = -8
(x²)³ = x^6 (the exponents multiply)
and of course, (y)³ = y³

On the bottom: (xy²z)² = x² y^4 z²
(-yz)² = y²z²
Multiplying these together, the exponents add and we get x² y^6 z^4.

\frac{-8x^6y^3}{x^2y^6z^4}

So, your reasoning is correct for what you have so far.

Your next step would be cancelling shared factors from the top and bottom.
Just like with regular fractions, if the numerator and denominator are divisible by the same number, you can divide them by it to simplify. (ex: 4/6 = 2/3)

Well, x^6 and x^2 are both divisible by x^2, right?
We can also cancel the y^3.

It might help to visualise the factors like this:

\frac{-8xxxxxxyyy}{xxyyyyyyzzzz}

Once you've cancelled out x² and y³ from each, you're left with

\boxed{\frac{-8x^4}{y^3z^4}}
