Answer:
B) -0.4 seconds
Step-by-step explanation:
Laps: 25
Goal: -10 seconds to all 25 laps combined (10 seconds difference => -10)
divide by total laps
-10 /25 = -0.4s difference each lap
Answer: NEITHER
Step-by-step explanation:
From the equation of lines given above, to know if relationships exist between the two lines, we must first determine that from their gradients or slopes.
From first equation
2x - y = 5,
y = 2x - 5
Therefore, m₁ = 2
From the second equation
3x - y = 5
y = 3x - 5
Therefore m₂ = 3
Recall, For the two lines to be parallel, m₁ = m₂ , and for the two line to be perpendicular, m₁m₂ = -1
since none fulfilled the conditions stated above, the answer then is
NEITHER
Answer:
c
Step-by-step explanation:
The simplest form is 4y+6?
you distribute the 4 to everything in the parentheses and then combine like terms so you would combine the 8 and -2
