Parallel lines have the same slope.
The answer is choice B.
Why?
Both equations share the same slope which is 1/2.
See it?
Answer:
The answer has no solution because it is infinite and that's your vairiable
Answer:
D
Step-by-step explanation:
Given
- 3 ÷ - 
Leave the first number, change division to multiplication and turn the fraction upside down, that is
= - 3 × - 
= 
= 
= 7
→ D
Answer:
The length of minor arc AB is
π ft
Step-by-step explanation:
The formula of the length of an arc in a circle is L =
× 2πr, where α is the central angle subtended by the arc, and r is the radius of the circle
∵ The radius of the circle is 4 ft
∴ r = 4
∵ ∠AOB is a central angle subtended by minor arc AB
∵ m∠AOB = 50°
∴ α = 50°
Substitute the values of r and α in the rule above
∵ L =
× 2π(4)
∴ L =
π
∴ The length of minor arc AB is
π ft
Lines k and n are perpendicular
The slope of line k is -6
Fact: The product of slopes of two perpendicular lines = -1
So the slope of line n = -1 ÷ -6 = 1/6
The correct choice is 'D.'
