Answer:
slope = 5/8
Step-by-step explanation:
use the slope formula to find the slope: 
Answer:
1. 2x-3
2.-4x+12
3.9x+3
4.-15x-12
5.2x-5
6.-11x
7.23x+42
8.-21x
9.-2x-12
10.4x-8
Step-by-step explanation:
F(x) = x² + x - 20 = x² + 5x - 4x - 20 = x(x + 5) - 4(x + 5) = (x + 5)(x - 4)
f(x) = 0 ⇔ (x + 5)(x - 4) = 0 ⇔ x + 5 = 0 or x - 4 = 0 ⇒ x = -5 or x = 4
Answer: C. x = -5 and x = 4.
Answer:
the order is Paco, Tim, Jenny, Maria
Step-by-step explanation:
Sin (a+b) = sin a. cos b + cos a. sin b
a= 50° and b=40°, then
sin(50+40) = sin 50° . cos 40° + cos 50° . sin 40°
sin(50+40) = sin 90° = 1 and
sin 50° . cos 40° + cos 50° . sin 40° = 1
