Answer:
x=1,y=3
correct answer is (1,3)
Step-by-step explanation:
We can quickly eliminate y by subtracting one equation from the other
(-2x+y=1)-(-4x+y=-1)
2x=2
x=1
plug x=1 into equation 1
-2(1)+y=1
y=1+2=3
Answer:
-- x intercept
-- y intercept
Step-by-step explanation:
Given
Required
Determine the x and y intercept
For x intercept.
Set
So, we have:
Collect Like Terms
Make x the subject
Hence, the x intercept is:
For the y intercept;
Set
So, we have:
Hence, the y intercept is:
49×12= 588
1. 50×10=500
2. 50×10+2= 502
3. 50×12-12= 588
4. 50+12-12=50
Another way to write 49×12 is 50×12-12
