discriminatn is b^2-4ac
a=4
b=12
c=9
discriinat is
12^2-4(4)(9)=
144-144
0
the discrminat is 0
Answer:
17/20x + 7/10 = y
Step-by-step explanation:
You can solve this equation by moving values until they fit the form y=mx+b (slope-intercept form).
- 17x - 20y = -14
- 17x + 14 = 20y
- 17/20x + 14/20 = y
- 17/20x + 7/10 = y
