Answer:
x²+(1/x²) = 47
Step-by-step explanation:
by identity : (a+b)² = a²+b²+2ab
(x+1/x)²= x²+(1/x)²+2(x)(1/x)
(x+1/x)²= x²+(1/x²)+2....(1)
since : (x²+1)/x = 7
(x²/x) +(1/x) = 7
x + (1/x )= 7
put the value for : x +(1/x) in (1) :
49 = x²+(1/x²)+2
x²+(1/x²) = 47
Answer:
Step-by-step explanation:
y=mx+c
So in this case, m is (-3/7), which is the slope.
(-3/7)(another slope)=-1
Another slope=3/7
A. The slope is -7/3
B. The slope is 3/7
C. The slope is -7/3
D. The slope is -3/7
Thus, the answer is the bottom of the left hand side, which is 3x-7y=14
