Well plug 0 in for x and solve for y and that is the vertex of your expression
1. x - y
2. xy
3. y / x
4. x+y
5. y= x-6
6. 6x =y
7. y-x
8. x/y
9. x+y= 6
10. xy= 6
Answer:
The answer is C 8 2/5 im pretty sure.
Answer:
one num = 6
another = 24
Step-by-step explanation:
One number = x
Another = 4x
Difference = 18
4x - x = 18
3x = 18 ; x = 18/3 = 6
4x+4y=-9
first change into yintercept form
y=-x-9/4
to find yintercept let x=0
y=-0-9/4
y=-9/4 or -2.25
to find xintercept let y=0
0=-x-9/4
x=-9/4
so the x and y coordinates are -2.25 and -2.25 respectively
