Bruce is solving a system of equations.
1 answer:
Answer:
Option 3,4,5 are correct.
Step-by-step explanation:
The system of equations are:
Multiply equation (2) with -3 and add with equation (1)
Value of y is 3
Putting value of y in eq(2)
Value of x is -2
So, Option 3,4,5 are correct.

Answer:
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).
