Answer:
y = -2x + 1.
Step-by-step explanation:
2y = x - 1
y = 1/2y - 1/2
If line X is perpendicular to line Y (the line where y = 1/2y - 1/2), the slope will be the negative reciprocal of line Y. That means that there will be a negative sign instead of positive, and the 1/2 will be flipped to become 2/1, which is 2.
So, the slope will be -2.
We now have y = -2x + c.
To find c, simply put in -1 for x and 3 for y.
3 = -2 * -1 + c
c + 2 * 1 = 3
c + 2 = 3
c = 1
So, the equation of the line is y = -2x + 1.
Hope this helps!
Answer:
271.25 gal
Step-by-step explanation:
Assuming the tank is oriented so that the quantity of oil is proportional to depth, the amount remaining is ...
(3 1/2 ft)/(8 ft) × (620 gal) = 271 1/4 gal
They are both isosceles triangles
The answer is B) x>3
13x - 4 < 12x - 1
13x > 12x + 3
x > 3
