non-linear functions
Average Rate of Change is used primarily with non-linear functions, since all linear functions have a constant rate of change.
I’m not sure about the problem on the right but for the first one: The length of AC is 21 units.
Answer:
Step-by-step explanation:
C. -11<x<-4
|-2x-15|<7 split into possible cases
- 2x - 15 < 7, - 2 x - 15 > 0
-(- 2x - 15 ) <7, -2x - 15 < 0 solve the inequalities
x>-11, x < -15/2
x< -4, x> -15/2 Find the intersections
[ -11, -15/2 ]
-15/2, -4] Find the union
[-11, -4 ] Simplify
-11<x<-4
Answer:
260°
Step-by-step explanation:
∠RPS +∠PSR +∠SRP= 180° (∠ sum of △PRS)
∠RPS +45° +60°= 180°
∠RPS +105°= 180°
∠RPS= 180° -105°
∠RPS= 75°
Let's focus on quadrilateral PQTU.
Sum of interior angles= (n -2) ×180°, where n is the number of sides
∠QPU
= ∠RPS +∠TPU
= 75° +25°
= 100°
Sum of interior angles= (4 -2) ×180°
m +n +p +100°= 2 ×180°
m +n +p +100°= 360°
m +n +p
= 360° -100°
= 260°
