Answer:
x = 5 or x = 1
Step-by-step explanation:
x² - 6x + 7 = 0
x² - 6x = -7
x² - 6x + 9 = -7 + 9 1/2 of the x term than square it and add it the both sides.
(x - 3)(x - 3) = 2
( x -3)² = 2
=
(x - 3) = ± 2
x - 3 = 2 or x - 3 = -2
x = 5 or x = 1
Answer:
A.
Step-by-step explanation:
Given,
The initial sprinting of Freya = 200 yards,
Also, She gradually increases her distance by 5 yards per day,
So, in second day her sprinting = 200 + 5 = 205 yards,
In third day = 205 + 5 = 210 yards,
In fourth day = 210 + 5 = 215 yards,
...................., so on,.....
Hence, the sequence that shows the given situation,
200, 205, 210, 215, .........
Which is an A.P.
That having first term, a = 200,
Common difference, d = 5,
Thus, the explicit formula for the given situation is,
Option A is correct.
