Answer:
C
Step-by-step explanation:
If you fill in x=0, you are left with the y intercept. In the picture you can see it must be larger than y=10. This invalidates answer A and D.
The x-coordinate top of the parabola ax²+bx+c=0 is given by y = -b/2a, so immediately we can see -b has to be positive. This leads you to answer C because -9x implies b=-9, and --9 is positive.
Answer:
it's 10
Step-by-step explanation:
Answer:y=-10
Step-by-step explanation:
y=-1/2 4(6(2)+3)-2y
+2y 6(2) +2y
3y=-1/2 4(12+3)
multiplie 4 times 12 and 4 times 3
3y=-1/2 48+12
add 48 and 12
3y=-1/2 60
divide -1/2 and 60
3y/3=-30/3
y=-10
