Answer:
A. -2x^2-2x-2
Step-by-step explanation:
(2x^2-5x-4)-(4x^2-3x-2)
distribute the minus sign
(2x^2-5x-4)-4x^2+3x+2
2x^2-5x-4
-4x^2+3x+2
-------------------------
-2x^2 -2x-2

Answer:
434 miles
Step-by-step explanation:
1hr = 62 miles
7hr = 434 miles
62 times 7 = 434
Mode (most occurring) - 4
mean (average) - 8
median (middle number from least to greatest) - 4
Answer:
s₁ > s₂
Is accurate comparison
Step-by-step explanation:
If we have two different point for a straight line the slope of such line is given by:
P₁ = ( x₁ , y₁ ) P₂ = ( x₂ , y₂ )
The slope of the line is
s₁ = (y₂ - y₁ ) / ( x₂ - x₁)
Then for the pairs of points:
P₁ (2 , 50 ) and P₂ ( 4 , 100)
y₂ - y₁ = 100 - 50 ⇒ y₂ - y₁ = 50
and
( x₂ - x₁ ) ⇒ 4 - 2 = 2
Then
s₁ = 50/2
s₁ = 25
In the second case
Points
P₁ ( 2 , 40 ) P₂ ( 4 , 80 )
s₂ = (y₂ - y₁ ) / ( x₂ - x₁)
y₂ - y₁ = 80 - 40 = 40
x₂ - x₁ = 4 - 2 = 2
s₂ = 40/2
s₂ = 20
Then
s₁ > s₂
Is accurate comparison
