B.
Step-by-step explanation:
The answer is B
Answer:
36hr 16min
Step-by-step explanation:
1pool/17hr - 1pool/32hr = 1 pool/xhr
1/17 - 1/32 = 1/x
Use common denomminator of 17*32 = 544
32/544 - 17/544 = 1/x
15/544 = 1/x
x = 544/15
x = 36 4/15 hr
x = 36hr 16min
Solving
S = 3F - 24
for F gives
S + 24 = 3F
(S + 24)/3 = F
The best choice is the last one:
F = (S + 24)/3
Answer:
4th option
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y =
x - 6 ← is in slope- intercept form
with slope m = 
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
= - 
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = -
and (a, b ) = (- 2, 5 ) , then
y - 5 = -
(x - (- 2) ) , that is
y - 5 = -
(x + 2)
