Answer:
w = 1.6
Step-by-step explanation:
Given w varies inversely as 
then the equation relating them is
w = 
← k is the constant of variation
To find k use the condition when x = 4, w = 4
k = w = 4 × 
= 4 × 2 = 8
w = 
← equation of variation
When x = 25, then
w = 
= 
= 1.6
Given : A florist currently makes a profit of $20 on each of her celebration bouquets and sells an average of 30 bouquets every week . and graph
To Find : Maximum profit , breakeven point , profit interval
Solution:
The maximum profit the florist will earn from selling celebration bouquets is $ 675
peak of y from Graph
The florist will break-even after Selling 20 one-dollar decreases.
at breakeven
Break even is the point where the profit p(x) becomes 0
The interval of the number of one-dollar decreases for which the florist makes a profit from celebration bouquets is (0 ,20).
after 20 , P(x) is - ve
Since there is nothing on the left side of the equation besides the absolute value, you have to take 6m out of the absolute value and create 2 separate equations. These 2 equation will be 6m = 42 and 6m = -42.
You solve the equations normally:
6m = 42 6m = -42 (inverse to get m by itself, do on both sides)
/6 /6 /6 /6
m = 7 m = -7
The answer is a solution set:
[7, -7]
Value of x is 2.
Step-by-step explanation:
- Step 1: Given that x+1/3 = x/2
Cross-multiply to find the value of x.
⇒ 2(x + 1) = 3x
⇒ 2x + 2 = 3x
⇒ x = 2
Answer:
y=-2x+17
