Answer:

  D.) a+2b

Step-by-step explanation:

The integers 'a' and 'b' can be any, so you can choose a couple and evaluate these expressions to see what you get. For example, we can let a=1 and b=0. For these values, the offered expressions evaluate to ...

  A) 3(0) = 0 . . . even

  B) 1 +3 = 4 . . . even

  C) 2(1+0) = 2 . . . even

  D) 1 +2(0) = 1 . . . odd

_____

<em>Additional comment</em>

These rules apply to even/odd:

  • odd × odd = odd
  • odd × even = even
  • even × even = even
  • odd + odd = even
  • odd + even = odd
  • even + even = even

Then A is (odd)(even) = even; B is (odd)+(odd) = even; C is (even)(whatever) = even; D = (odd)+(even) = odd.

Calculate the slope of the line that contains the points: (2,-3) and (6,-3)
pshichka [43]

Answer:

Step-by-step explanation:

Slope (m) =

ΔY

ΔX

= 0

θ =

arctan( ΔY )

ΔX

= 0°

ΔX = 6 – 2 = 4

ΔY = -3 – -3 = 0

Distance (d) = √ΔX2 + ΔY2 = √16 = 4

Equation of the line:

y = 0x – 3

When x=0, y = -3
