Two times the difference of x and seven plus ten
Answer:
The length of side AB is 5 units
Step-by-step explanation:
* Lets revise how to find the distance between two points
- If there are two points their coordinates are (x1 , y1) and (x2 , y2),
then we can find the distance between them by this rule:
d = √[(x2 - x1)² + (y2 - y1)²]
- Now lets solve the problem
∵ A = (4 , -5)
∵ B = (7 , -9)
- To find the length of AB use the rule of the distance above
- Let point A is (x1 , y1) and point B is (x2 , y2)
∵ x1 = 4 and x2 = 7
∵ y1 = -5 and y2 = -9
∴ AB = √[(7 - 4)² + (-9 - -5)²]
∴ AB = √[(3)² + (-4)²]
∴ AB = √[9 + 16] = √25 = 5
* The length of side AB is 5 units

Answer:
b = 16.5
Step-by-step explanation:
Multiply the equation by 11b/9.
b = 13.5(11/9)
b = 16.5
Answer:
Step-by-step explanation:
The equation of the line in point-slope form is:
Where m is the slope and is a point of the line.
The slopes of two perpendicular lines are opposite reciprocal, then the other slope is:
m=
Substitute the slope and the given point into the equation, then you obtain:
