Answer:
Step-by-step explanation:
the solution to the system
= find the intersection of two lines
method( one )
solve the equations ( find(x , y) )
( 1 ) y = -x +3
( 2 ) y = x - 3
now , we let ( 1 ) + (2 )
we have 2y =0 ,thus y = 0
from ( 1 ) y = - x +3 , we know y = 0 ,
we rewrite ( 1 ) as 0 = -x + 3,thus x = 3
method( two)
see the intersection point of two lines
so the ans is B.(3 , 0)
You need to flip the shapes over the x-axis and move over -8 to 0

Answer:
The ways in which he can make selection = ![10\times 9 =90](https://tex.z-dn.net/?f=10%5Ctimes%209%20%3D90)
Step-by-step explanation:
Student is having a list of
books.
Assuming that the student can't read the same book twice.
The student has
choices to make for an outside reading requirement,for his 1st choice, he had
books to choose from; for his 2nd, he has
books left to choose from therefore the total permutations of his choices are ![=10\times 9 =90](https://tex.z-dn.net/?f=%3D10%5Ctimes%209%20%3D90)
So the total ways in which the student can make his selection = ![90](https://tex.z-dn.net/?f=90)
Answer: A is 200 + 45h = c B is $425
Step-by-step explanation:
45 * 5 = 225 Now add 200. 225 + 200 = $425
