The quotient to p/q = -3 is 4
Answer:
x=3; y=5
Step-by-step explanation:
y=x+2
y=3x-4
so x+2=3x-4
2x=6
x=3
because y=x+2
x=3
so y=3+2
=5
Answer:y=3x+6
Step-by-step explanation:
Answer:
√a(√a + 2) a - 2√a
----------------- = -----------------
a - 4 a - 4
Step-by-step explanation:
I am assuming that by "sqrt(a)/sqrt(a)-2" you meant:
√a
----------
√a - 2
To rationalize the denom., multiply numerator and denom. of this fraction by the conjugate of √a - 2, which is √a + 2:
√a(√a + 2)
-----------------
a - 4
3/4 - 3/10
Convert to like denominators:
15/20 - 6/20
Subtract the numerators:
9/20
