What is the orthocenter of the triangle with two altitudes given by the lines x = -1 and y = x + 1. : (0, -1) (-1, -2) (-1, 0) none of these

Orthocenter is the point of concurrence of the altitudes of the triangle.

This means Orthcenter is the point where the altitudes intersect.

Here one altitude is x = -1

The other altitude is y = x + 1

Substituting x = -1 in y = x + 1

We get

y = -1-1=0

Hence the point of intersection of the altitudes is (-1,0)

The orthocenter of the triangle whose altitudes are x = -1 & y = x+1 is (-1,0)

(-1,0) which is Option c) or the third option is the right answer.

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6

f(x)=4
