E Solve the system of equations by finding the reduced row-echelon form of the augmented matrix for the system of equations.
x-2y + 3z = -2
6x + 2y + 2z = -48
x + 4y + 3z = -38
(-5, -6, -60)
c. (-5, -6, -3)
b. (-52 – 60, – 32)
d (-52, -6, -60)

y=mx+b

step-by-step explanation:

m is slope, b is y-intercept

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.

step-by-step explanation:

step-by-step explanation:

rectangles are made up of 4 right angles, which means that a side and a base meet perpendicular to one another.   their slopes then have to reflect perpendicular slopes.   perpendicular slopes are opposite reciprocals of one another.   for example, if the slope of one line is +2/3, then the perpendicular slope to that would be -3/2.   so we look for that combination in our choices.

all of them satisfy that condition (so what's the question, i guess? )
