Answer:
3x + y = 20
Step-by-step explanation:
The equation of line passing through two points is determined by formula:
Here, (x₁ , y₁) = (4, 8)
and (x₂, y₂) = (6, 2)
Putting these value in above formula. We get,
⇒ 
⇒ ( y - 8) = -3 (x - 4)
⇒ y - 8 = -3x + 12
⇒ 3x + y = 20
which is required equation.
Answer:
Step-by-step explanation:
$6/(2 DVDs) = $3/DVD, and $8/(4 CDs) = $2/CD
a DVD costs $3
a CD costs $2
Ling bought 4 DVDs and 2 CDs for 4×$3 + 2×$2 = $16.
Pierre bought d DVDs and c CDs for $20.
d is 0, 2, 4, or 6
c = (20-3d)/2
(d,c) = (0,10), (2,7), (4,4), or (6,1)
[all of the above] 15kg box moving at same speed as 10kg box obviously has more inertia/energy and ogbects in motion will keep going at same velocity until acted upon by an outside force such as friction or it slamming into stuff and such
Let p represent # of pages in the book.
Then (1/4)p = 67. Solve for p by mult. both sides of this equation by 4:
p = 268 (pages)
1 mile = 1.609344... kilometer
2,180 miles = (1.609344... x 2,180 km)
