Answer:
140
Step-by-step explanation:
you have to first multiply them
-140
since it has to be an aditive inverse you write the opposite
140
You see one point is (-3,1). The next point that you see is (0,2). You can do rise/run
For 1 to go to 2, you need to go up one. For -3 to get to 0, you need to run 3. So, the answer would be rise/run, or
1/3
Answer:
9/21
Step-by-step explanation:
9/21 as a fraction is equal to 3/7
9/21 has a common factor of 3, allowing it to simplify down to 3/7
-3x-2=19
move -2 to the other side
sign changes from -2 to +2
-3x-2+2=19+2
-3x=19+2
-3x=21
divide both sides -3 to get +x
-3x/-3=21/-3
Cross out -3 and -3, divide by 3 and then becomes -1*-1*x=x
divide by 3 for 21/-3
21/3=7
-3/3=-1
7*-1=-7
Answer:
x=-7
