Answer:
A) 60
Step-by-step explanation:
P = 5+5+11+9+(5+11)+(9+5)
P = 60
B. slope is -1/2
This is because the m-value aka the slope is always the reciprocal if the line is perpendicular
Answer:
(4,-3)
Step-by-step explanation:
Multiplying the bottom equation by -6, we get -6x+12y=-60.
Adding this to the first equation gives 15y=-45, and thus y=-3.
So, it follows that 6x+3(-3)=15, and thus x=4.
Answer: 99
Explanation: 9+9 = 18
and when you switch the order of the digits, it is still 99.
