Answer:
y = 2x-2
Step-by-step explanation:
First find the slope of the line
x+2y=6
2y = -x+6
y = -1/2x +3
This is in slope intercept form ( y = mx+b) so -1/2 is the slope
We want a line that is perpendicular so take the negative reciprocal of the slope
- ( 1/ (-1/2)) = 2
The slope of the perpendicular line is 2
y = 2x+b
Substitute the point into the equation
8 = 2(5) +b
8 = 10+b
-2 =b
The equation of the line perpendicular is
y = 2x-2
(In English), your question would state the following:
<span>Calculate the circumference and circumference of the circle entered in a square 8 cm long.
</span>
So when finding the answer this this question, we know that the circumference would be the complete area of a circle.
So, I believe we would want to find what is the radius and the diameter that would make this circumference 8

.
The radius would then be (1.274).

Now in your own language (Croatian).
<span>Dakle, kad pronađemo odgovor na ovo pitanje, znamo da bi opseg bio cjelokupno područje kruga.
Dakle, vjerujem da bismo željeli otkriti što je radijus i promjer koji bi ovaj opseg mogao učiniti 8cm.
Radijus bi onda bio (1.274).</span>
The only thing you should do is to multiply 2/3 by 120 so you will have 2*120/3 = 80 :)))
i hope this is helpful
have a nice day
Answer:
x = ±
i
Step-by-step explanation:
subtract 64 from both sides
9x² = - 64 ( divide both sides by 9 )
x² = -
( take the square root of both sides )
x = ±
= ±
i
