- 1x+y+z=-4

For the following matrix, which of the following matrix operations would result in 241 = 1?
A. Multiply row 2 by-1 and add it to row 1.
B. Multiply row 3 by -4 and add it to row 1.
C. Multiply row 1 by -1/2
D. Multiply row 1 by 1/2

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9

the answer is a

step-by-step explanation:

because if you put 1 in to the square root of x it equals 300.

b

step-by-step explanation:

it have 5 sides and 5 identicle angle.the rest does not have the same property as b.
