Answer:
Perpendicular
Step-by-step explanation:
To tell if the lines are perpendicular/parallel, you must look at the slope, but in this case, you must first get y by itself, like so:
3x + 7y = 15
-3x - 3x
___________
7y = -3x + 15
<em><u>Divide both sides by 7:</u></em>
y = ![\frac{-3}{7}x + \frac{15}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B-3%7D%7B7%7Dx%20%2B%20%5Cfrac%7B15%7D%7B7%7D)
<em><u>Now the other equation:</u></em>
7x - 3y = 6
-7x -7x
_________
-3y = -7x + 6
<em><u>Divide both sides by -3:</u></em>
y = ![\frac{7}{3} x - 2](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B3%7D%20x%20-%202)
You can see that the lines are perpendicular because the slopes (
and
) are opposite reciprocals.

FORMULA:
ANSWER:
We are given new side of square i.e, 2s + 3.
So, Area = (2s + 3)²
- (2s)² + (3)² + 2 × 2s × 3
- 4s² + 9 + 12s
Hence, The area of the new graph is a perfect square trinomial: __4__s² + __12__s +__9__.
Answer:
y^12/216x^6
Step-by-step explanation:
First Im distrubiting the powers.
((6^-3)[(x^2)^-3][(y^-4)^-3])
(216^-1)(x^-6)(y^12)
Move the negative exponents
y^12/216x^6
The slope is 1
Slope = change in y / change in x
Slope = 1 - - 5 / 5 - - 1
Slope = 1 + 5 / 5 + 1
Slope = 6 / 6
Slope = 1
