2x + y - Z=-8 2y+ 3z= -6
x+y+z=-4
For the following matrix, which of the following matrix operations would result in a = 1?
Multiply row 2 by -1 and add it to row 1.
Multiply row 3 by -4 and add it to row 1.
Multiply row 1 by -1/2
Multiply row 1 by 1/2

step-by-step explanation:

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)

the area of the rectangle is 35units^2.

step-by-step explanation:

graph it and find the distance.

it is a 5*7 rectangle.

therefore the area is 35units^2.
