Answer:
x = 269/15
Step-by-step explanation:
(3x - 5) / 6 - (4 + x) / 7 = 5
7(3x - 5) - 6(4 + x) = 5(42)
21x - 35 - 24 - 6x = 210
15x - 59 = 210
15x = 269
x = 269/15
Answer:
f(x)=start fraction 4 over x squared End fraction minus start fraction 2 over x end fraction +1
Answer:
x = ±sqrt(y-11)
Step-by-step explanation:
y = x^2 +11
Subtract 11 from each side
y -11 = x^2 +11-11
y-11 = x^2
Take the square root of each side
±sqrt(y-11) = sqrt(x^2)
±sqrt(y-11) = x
Answer:
D
Step-by-step explanation:
x/(x²+3x+2) - 1/[(x+2)(x+1)]
x² + 3x + 2 = x² + 2x + x + 2
= x(x + 2) + (x + 2)
= (x + 2)(x + 1)
= x/[(x+2)(x+1)] - 1/[(x+2)(x+1)]
= (x-1)/[(x+2)(x+1)]
= (x-1)/(x²+3x+2)
we know that
total of sum of arc is 360
so, sum of both arc must be 360
so, we get
now, we can solve for x
