F(x) = 1.5x + 50
if you use 5GB per month, you should pay
f(5) = 1.5(5) + 50 = $57.50
Answer:
(b² + 1) (b - 1)
Step-by-step explanation:
= b³ - b² + b - 1
= b² (b - 1) + 1(b - 1)
= (b² + 1) (b - 1)
Answer:
b
Step-by-step explanation:
The equation of a line passing through the origin is
y = mx ( m is the slope )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (0, 0 ) and (x₂, y₂ ) = (3, 4 )
m = 
= 
y = x → b
Answer:A is a subset of D
Step-by-step explanation:
Because A has what it is contained D
Since 5×4 is in brackets, we start with that
so 2÷3 (20)÷3+6÷7
we do ×/÷ first from the left
so 4.44+ 0.8571428571 = 5.301
