set them equal to each other
x²+1=x+1
minus 1 from both sides
x²=x
minus x both sides
x²-x=0
factor
x(x-1)=0
set each to 0
x=0
x-1=0
x=1
subsitute back to find y values
y=x+1, y=0+1, y=1, one point is (0,1)
y=x+1, y=1+1, y=2, another point is (1,2)
the 2 points of intersection are (0,1) and (1,2)
Answer:
4736
Step-by-step explanation:
1) 100 divided by 5 is 20
2) 20 times 3 is 60
3) 60 times 79 is 4740
4) 4740 subtract from 4 is 4736
5) Answer is 4736
Answer: (7,5) X=7 and Y=5
Explanation:
Add the two equations together to eliminate y from the system.
x-y=2 + x+y=12
= 2x = 14
Divide both sides by 2
x=7
Substitute the value found for x into one of the original equations to solve for y
(7)-y=2
Move all terms to one side to make it easier
-y=2-7
Subtract
y=5
