You would first substitute -7 for m and 2 for n. It would look like this: 4| -7-2 | . we first solve the absolute value because it is the first step in PEMDAS or order of operations. -7-2 is equal to -9. Our equation should look like this now: 4 |-9| . we solve the absolute value portion, the absolute value of a negative number is the the same number but positive. the absolute value would be 9. (we just take the negative symbol off). we now have 4 x 9. This is equal to 36.
36 is the answer.
Answer:
(2,1,0)
Step-by-step explanation:
3x+3y+6z=9
3(2)+3(1)+6(0)=9
6+3+0=9
6+3=9
9=9
x+3y+2z=5
x(2)+3(1)+2(0)=5
2+3+0=5
2+3=5
5=5
3x+12y+12z=18
3(2)+12(1)+12(0)=18
6+12+0=18
6+12=18
18=18
