Y=mx+b, where m is the slope and b is the y-intercept, we are told m=-1/2 so
y=-x/2+b, using point (-6,2) we can solve for b
2=-(-6)/2+b
2=3+b
b=-1 so the line is:
y=-x/2-1 or more neatly:
y=(-x-2)/2
Answer:x^4-2x^3-17x^2+8x+72
Step-by-step explanation:
X=3 x=-3 x=4 x=-2
(X-3)(x+3)(x-4)(x+2)
(X^2-9)(x^2-2x-8)
X^4-2x^3-8x^2-9x^2+8x+72
X^4-2x^3-17x^2+8x+72
20/9 is the answer that I got
The radius of a circle is half the length of the diameter so
radius=1.5m
Length of room, l = 3x + 1 ft.
Breadth of room, b = x² -1 ft.
Now, it is given that university wants each room to have 195 ft² of living space.
So,
So, above equation has two complex root and one real root i.e x = 4.08 ft .
Therefore, Length of room is 13.24 ft and breadth is 15.65 ft.
Hence, this is the required solution.
