Use Brainly to find the right answer :) tha the what I do all the time
Just put the coefients in to a matrix
1x-6y-3z=4
-2x+0y-3z=-8
-2x+2y-3z=-14
mulstiply 2nd row by -1 and add to 3rd
divde last row by 2
multiply 2rd row by 6 and add to top one
multiply 1st row by -1 and add to 2nd
divide 2nd row by -3
mulstiply 2nd row by -1 and add to 1st row
divide 1st row by -3
rerange
x=-2
y=-3
z=4
(x,y,z)
(-2,-3,4)
B is answer
Answer:
-5
Step-by-step explanation:
t - 3 > -8
t > -8 +3
t > -5
hope it helps
12c^9 + 28c^7
first we find the GCF of 12 and 28.....thats gonna be 4
then, for the exponents.....take the smallest one...it is c^7
so we factor out 4c^7
4c^7(3c^2 + 7) <===
