You just do 3 times 4 and you get 12
When a = 3i - 2j, and b = -4i + 10j. Plug in the corresponding terms with the corresponding variables.
(-4i + 10j) - (3i - 2j)
Distribute the negative to each variable in the second parenthesis
- (3i - 2j) = -3i + 2j
Simplify.
-4i + 10j -3i + 2j
-7i + 12j
-7i + 12j, or (A) is your answer
hope this helps
Answer:
[See Below]
Step-by-step explanation:
You haven't attached any equations so I can't solve this however:
Parallel lines when plotted always have the same gradient.
The general form of line is y = mx + c where "m" is the gradient.
So parallel lines will have "m" to be the same value.
Examples are: y = 6x + 4 and y = 6x - 99
: y = -4x + 2 and y = -4x + 5
You can multiply 3 and 6 together then divide the product by 2
(6*3)/2=18/2=9
