Answer:
D. y+15 = 4/5(x+5)
Step-by-step explanation:
A line contains the points (8,9) and (-12, -7).
(y2 - y1) = m(x2 - x1)
(9 - (-7))= m (8 -(-12))
16 = m*20
m = 16/20 = 4/5
Given line has slope m= 4/5.
Parallel line has the same slope m = 4/5.
Point-slope equation is (y - y1) = m(x - x1).
We have slope m = 4/5, and point (-5, -15).
So,
(y - (-15)) = 4/5(x - (-5))
y+15 = 4/5(x+5)
Answer:
Step-by-step explanation:
perimiter=2(Length+Width)
P=2(L+W)
solve for L
distribute
P=2L+2W
minus 2W
P-2W=2L
divide by 2
\frac{P-2W}{2}=L
given that P=34 units and W=6.5 units
\frac{34-2(6.5)}{2}=L
the equation would be L=p2w/2 or L= p/2=w
Answer:
Thus, the coffee shop is willing to supply 6 pounds per week at a price of $4 per pound.
Step-by-step explanation:
We are given the following information in the question:
The marginal price per pound (in dollars) is given by:

where x is the supply in pounds.

The coffee shop is willing to supply 9 pounds per week at a price of $7 per pound.
Thus, we are given that
P(9) = 7
Putting the values, we get,


Now, we have to find how many pounds it would be willing to supply at a price of $4 per pound.
P(x) = 4

Thus, the coffee shop is willing to supply 6 pounds per week at a price of $4 per pound.
50 secs
as $90÷5hrs= 18 $ per hrs
$18÷60min=$0.30 per min
$0.30÷60sec=$0.005 per sec
$0.25÷$0.005= 50sec to make $0.25
so 50sec is the answer
