2y=-6x+8
First, the slope of any equation, is always the coefficient with the variable "x".
So, the slope for this line, is -6x.
To get rid of the coefficient with y, we need to divide 2, from both sides of the equal sign.
<u>2y=-6x+8</u>
2
y=-3+4
Now that we have our new equation, we can see that the slope of our line has also changed, from -6x to-3x. Because -6÷2=-3.
And to find the perpendicular slope, you change the reciprocal of the slope so from -3 to 1/-3 and then you change the sign of the slope so from 1/-3 to 1/3. That is your final answer.
The answer is 2) 1/3.
Answer:
Option 3
Step-by-step explanation:
(x² + 10x + 25 - 25) + (y² - 20y + 100 - 100) + 44 = 0
(x + 5)² + (y - 10)² - 25 - 100 + 44 = 0
(x + 5)² + (y - 10)² - 81 = 0
There ya go! Hope this helped
6.5 gallons = 24.6052 liters
6.5 has 2 significant figures, so it would need to be 25 liters
Answer:
2.5 meter
Step-by-step explanation:
in a right triangle, tan of an angle = opposite side /adjacent side
tan 70° = x/ 0.9 , multiply both sides by 0.9
0.9 * tan 70° = x, solve on a calculator
x ≈ 2.5 m
