Step-by-step explanation:
Having drawn the line, Kendall must verify that the point P belongs to the line y = 2x-1 and then calculate the distance between A-P and verify if it is the closest to A or there is another one of the line
Having the point P(3,5) substitue x to verify y
y=2*(3)-1=6-1=5 (3,5)
Now if the angle formed by A and P is 90º it means that it is the closest point, otherwise that point must be found
and we found the distance PQ and QA
; ,
be the APQ triangle we must find <APQ through the cosine law (graph 2).
Answer:
Justin worked as a babysitter 8 hours and worked as a lifeguard 2 hours last week
Step-by-step explanation:
Let
x ----> number of hours worked as a babysitter last week
y ----> number of hours worked as a lifeguard last week
we know that
----> equation A
----> equation B
Solve the system by substitution
Substitute equation B in equation A
solve for y
Find the value of x
therefore
Justin worked as a babysitter 8 hours and worked as a lifeguard 2 hours last week
