53 / 100 = 0.53
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:
(-11, -12)
Step-by-step explanation:
we need one variable to x out
on the note of x, lets cancel out the xs
6x+3y=-102
3x+y=-45 < same as 6x+2y-90
6x+3y=-102
-
6x+2y=-90
y=-12
substitute y in
3x-12=-45
3x=-33
x=-11
(-11, -12)
