Consider the following system of linear equations. 2x −z =−1 3y −z =3 4x +5y −3z =5 Solve the system by completing the steps below to produce a reduced row-echelon form. R1, R2, and R3 denote the first, second, and third rows, respectively. The arrow notation → stands for "replaces," where the expression on the left of the arrow replaces the expression on the right.

the answer is d. (1.2, -4.7) on edgn

hope this !

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.

25% is the answer

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
