Multiply 80 miles by 4 hours to get 320 miles for 4 hours.
Answer:
Step-by-step explanation:
The function is f(x) = -4x²+10x-8
Let Δ be our the dicriminant
- Δ= b²-4ac
- b = 10
- a = -4
- c = -8
- Δ = 10²-4*(-4)(-8)
- Δ = 100-128
- Δ = -28
The value of the discriminant is -28 and since it is negative this function has no real zeroes

Answer:
slope = - 
Step-by-step explanation:
Parallel lines have equal slopes thus the slope of a parallel line will be equal to the slope of PQ
To calculate slope m use the slope formula
m = 
with (x₁, y₁ ) = P(- 2, 4) and (x₂, y₂ ) = Q(6, - 2)
m =
=
= -
