x=3+√2 or x=3−√2

Step-by-step explanation:

For this equation: a=1, b=-6, c=7

1x2+−6x+7=0

Step 1: Use quadratic formula with a=1, b=-6, c=7.

x=

−b±√b2−4ac

x=

−(−6)±√(−6)2−4(1)(7)

2(1)

x=

6±√8

x=3+√2 or x=3−√2

it would take 7/10 of an hour too fill the pool.

step-by-step explanation:

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
