Answer:
Substitute (x+4)2−16 ( x + 4 ) 2 - 16 for x2+8x x 2 + 8 x in the equation x2+y2+8x−6y=24 x 2 + y 2 + 8 x - 6 y = 24 . (x+4)2−16+y2−6y=24 ( x + 4 ) 2 - 16 + y 2 ...
Step-by-step explanation:
Answer:
<em>y = (x - 4) - 4 </em>
Step-by-step explanation:
m = 
(- 2, - 10)
(4 , - 4)
m = 
= 1
y + 4 = (x - 4) ⇒ <em>y = (x - 4) - 4</em>
Inverse variation means y=k/x (direct variation is y=kx) so we can use the info given to find the constant k
y=k/x
6=k/900
k=6(900)
k=5400 so the equation is:
y=5400/x or more accurately for this problem
t(v)=5400/v then:
t(800)=5400/800
t(800)=6.75 hours
Answer:
- the way its set up its kind of confusing ↑
Step-by-step explanation:
1/2 = 4/8
3/8 = 3/8
8 is the common denominator between these two fractions
