Answer:
Step-by-step explanation:
The slope of straight line PR where P(2,3) and R(5,-1) are two vertices of triangle PQR will be = 
Therefore, the slope of the altitude passing through Q(-1,1) will be 
{Since, the product of slopes of two perpendicular straight line is -1}
So, equation of the altitude is 
where c is a constant.
Now, putting x = -1 and y = 1 in the above equation we get
⇒ 
Therefore, the equation of the altitude is (Answer)
Answer:
um ok
Step-by-step explanation:
Let's break down all the information we receive from the question.
One pair of shoes= three times as much as a scarf
One pair of shoes and one scarf= $32
We need to make an equation where 3s= pair of shoes and s=scarf. We then need to put one pair of shoes + one scarf = 32.
3s+s=32
Now add.
4s=32
You could use 4s=32 (or 32÷4=s).
After 6 months, It will be 2/23/2018
Answer:
The sum of the first 51 terms of the sequence is 6018
Step-by-step explanation:
AP: −282,−266,−250,−234,...
First term = a = -282
Common difference = d = 
Common difference = d = -266-(-282)=-250-(-266)=16
Formula of sum of first n terms =
Substitute n = 51
So,
Hence the sum of the first 51 terms of the sequence is 6018
