Given:
DE contains the points D(1, -2) and E(3, 4).
FG contains the points F(-1, 2) and G(4, 0).
To find:
Is DE perpendicular to FG.
Solution:
Slope of DE:
Here 
m = 3
Slope of FG:
Here 
<em>Two lines are perpendicular if product their slopes are -1.</em>
Slope of DE × Slope of FG
≠ -1
The solution is no, because the product of the slopes is not -1.
Answer:
Step-by-step explanation:
<u>Use ratios to find the required value:</u>
- 1/48 : 1/4 = 1 : x
- 1/12 = 1/x
- x = 12 miles
Store should sell about 31 bicycle for average price of $135 each bicycle.
Step-by-step explanation:
- To find bike we need Algebra to solve the equation.
- when x = 1 , Y = 135 *x
- When x 2 , Y = 135 *2
- Formula you could apply to go for break even y = 135*x
- Bicycle store pays about $4200
- Algebra used for every business and working to make easy task.
- It takes about 31 bicycle a month to get into break even.
- Every store needs break even to not incur lost.
- Break even point is equilibrium between income and expenses.
