Answer:
x = 7 or x = 1
Step-by-step explanation:
For this equation: a=-1, b=8, c=-7
−1x2+8x+−7=0
Step 1: Use quadratic formula with a=-1, b=8, c=-7.
x= ( −b±√b2−4ac
)/2a
x=
(−(8)±√(8)2−4(−1)(−7))/ (2(−1)
)
x= (−8±√36
)/-2
x=1 or x=7
Answer:
It is 4/11
Step-by-step explanation:
Let x = 0.363636363636
Now as there are two digits repeating immediately after decimal point, we multiply above by 100 and get
100x = 36.363636363636
Now subtracting first equation from second we get
99x = 36
and hence
x = 36/ 99
= (9 × 4) / (9 × 11)
which then equals
= 4/11
The maximum value of the function is 5/4.
