Multiply every coordinate by the scale factor 3
(-1,2,0) ----> (-3,6,0) is the answer
Answer:
y=2, x=-1
Step-by-step explanation:
We can add the two equations together to eliminate x:
6x+5y+(-6x)+7y=4+20
12y=24
y=2
We plug y into the first equation and get
6x+5(2)=4
6x+10=4
6x=-6
x=-1
3 6 7 4
+ 6 7 8 9

10 4 6 3
C) 7 pounds 10 ounces 7 5/8
3 ponds + 4 pounds = 7 pounds
8 ounces + 2 ounces = 10 ounces
16 ounces in a pound
7 pounds 10/16 ounces
reduce '10/16' to '5/8'
