Answer:
It turns out that all three altitudes always intersect at the same point - the so-called orthocenter of the triangle. The orthocenter is not always inside the triangle. If the triangle is obtuse, it will be outside. To make this happen the altitude lines have to be extended so they cross.
Answer:
y^2+xy+x+3y+2
Step-by-step explanation:
first of all we have to multiplies the y in the second bracket for all numbers in the first bracket.
so we have:
xy+y^2+2y
now we have to do the same with 1
x+y+2
now we have to unite the two solutions
xy+y^2+2y+x+y+2
at least we have to added up the similar terms (that have the same literal part)
y^2+xy+x+3y+2
Answer:
yes because it is in the positive side
You can rent a paddleboat at Lake Isabel. The cost is $15 for the first hour - then $9 for each hour after that. Use this information to complete the following: Write an equation in slope intercept form that represents the cost (y) of the rental based on the number of hours (x) you rent it. b) What is the y intercept of your equation? c) What does this mean in the context of the situation? d) What is the slope of your equation? e) What does this number mean in the context of the situation? f) Graph the line that is represented by your equation. Make sure to clearly label the axis. g) How much will it cost to rent the paddleboat for 4 hours? Show how you found your answer algebraically. Also show and explain where this information can be found on your graph.
2 (6) - 3 (-3) , 12 - -9 , 12 + 9 , 21
