Answer:
1,050,000
Step-by-step explanation:
Question 1:
Substitution.
x+y=2
y=-x+2
2x+(-x+2)=4
x=2
(2)+y=2
y=0
Solution: (2,0)
There is one solution
Question 7 is too confusing, just find where the points intersect at (-5,2).
Question 9:
Elimination.
(-1)y=2x+6
y=2x+2
New: -y=-2x-6
0=-4
No Solution
Question 11:
Just look at explanations.
It's (5,17) both lines etc..
Answer:
- To establish a ratio relation you must see the difference hence 9:4 =2.25
- So 2.25, 2.5, 2.11, 3.33, 2.85
