What is the orthocenter of the triangle with two altitudes given by the lines x = -1 and y = x+1

Mathematics

Answer: (-1,0)

------------------------------------------------

Explanation:

A quick method is to simply look at the graph and notice the two altitudes cross at (-1,0)

----------

A longer method involves a bit of algebra but its not too bad

y = x+1
y = -1+1 ... plug in x = -1 (ie replace x with -1)
y = 0
So when x = -1, the value of y is y = 0
They pair up to get (x,y) = (-1,0) which confirms what the graph is showing

Step-by-step explanation:

first of all, g(x) has only negative functional result values (y) except for 0.

and a square is always positive.

so, the only possible right answers are the ones that include a minus ("-") sign.

the graph shows us that g(x) goes through the points (1, -3) and (-1, -3).

so, which equation turns an x = 1 into an y = -3 ?

therefore, the right answer must be D.

g(x) = -3x²

it works for both points :

-3 = -3×1² = -3 correct

-3 = -3×(-1)² = -3×1 = -3 correct

Paula is now four times the age of Lynn Lynn will be 16 in 10 years how old was Paula four years ago show your work
Dovator [93]
Greetings!

"<span>Paula is now four times the age of Lynn. Lynn will be 16 in 10 years. How old was Paula four years ago?"

If Lynn will turn sixteen in ten years, she must be 6 at the current moment:
16-10=6

Since Paula is 4 times the age of Lynn, Paula must be:
6(4)
=24

24-4
=20 

Paula was 20 years old, 4 years ago.

Hope this helps.
