Consider Adam's income statement. Which shows how to calculate
Adam's net income?
$1,310 - $3,100 = $1,790
$3,100 + $1,310 = $4.710
$3.100 - $1,310 = $1,790
$4,710 - $3.100 = $1,610
The answer is $3,100-$1,310=$1,790

C) $3,100-$1,310=$1,790

Step-by-step explanation:

Expenses :

150+850+110+70+90+40= $1,310

Income :

$3,100

$3,100  -  $1,310  =  $1,790

3. parallelogram

step-by-step explanation:

we turn each of our sides into direction vectors

ab=b-a=(3 - 7, 1 - 0) = (-4, 1)

bc=c-b=(1,6)

cd=d-c=(4,-1)

da=a-d=(-1,-6)

we see how the opposite sides have negated direction vectors; this is characteristic of a parallelogram.   we have congruent sides ab=cd and bc=da with unequal lengths because 1^2+6^2 is different from (-4)^2+1^2.   so it's not a square or a rhombus.  

we check the dot product of direction vectors of adjacent sides.   we have

ab dot bc = -4(1) + 1(6) = 2

that's not zero so the sides are not perpendicular.   we've ruled out rectangle.

the direction vectors indicate two pairs of congruent parallel sides, so we choose parallelogram over trapezoid.

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )
