The common ratio is you times each number by 2 each time.
Answer:
A B B C
Step-by-step explanation:
Answer:
y = - 
x + 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 6x - 1 ← is in slope- intercept form
with slope m = 6
Given the slope m of a line then the slope of a line perpendicular to it is
= - 
= - , thus
y = - x + c ← is the partial equation
To find c substitute (- 6, 4) into the partial equation
4 = 1 + c ⇒ c = 4 - 1 = 3
y = - x + 3 ← equation of perpendicular line
Answer:
Perimeter = 23.692 units
Step-by-step explanation:
Perimeter = sum of all his sides
then:
Perimeter = 4.15 + 7.092 + 12.45
Perimeter = 23.692 units
