Using Pythagorean theory : a²+9²=15²
=> a²=225-81=144
=> a = √144 = 12
Step-by-step explanation:
Answer:
0,4,8,12,16
Step-by-step explanation:
so for the value of x- just substitute it into the equation
so -2
8+4(-2)
8-8=0
The slope of the perpendicular line b is -1/7 if the slope of the perpendicular line a is 7.
According to the question,
Line 'a' is perpendicular to the line 'b'. If the slope of the line 'a' is 7.
The condition of slopes if two lines are perpendicular m₁ m₂ = -1
(7)(m₂) = -1
m₂ = -1/7
Hence, the slope of the perpendicular line b is -1/7 if the slope of the perpendicular line a is 7.
