Answer:
C
Step-by-step explanation:
perpecndicular means they intersect in right angle which is 90°, no matter how long lines are.
(3*2)(10^2 * 10^3) = 6*10^5
The systems will intersect at (1,-4), and i think the system has infinite solutions (not sure)
First, you have to apply the order of operations.
Division and multiplication come first here and they go from left to right. So,
56/7 = 8
7*3 = 21
Then, the addition.
8 + 21 = 29.
So the value of your expression is 29.
