I’m no math teacher but I think it’s 13
Answer:
It will have one solution.
Step-by-step explanation:
The line will meet at a point if extended to give a unique solution.
C(3) = -0.09(3)² + 3.5(3) + 8
= -0.09 * 9 + 10.5 + 8
= -0.81 + 18.5
= 17.69 parts per million
8307 divided by 12.75 is about 651.53
651.53 x 11.95 is about $7785.78
Answer:
1) y = (-13/6)x + (37/3)
2) -⅔
3) negative
Step-by-step explanation:
1) slope = (1.5-8)/(5-2) = -13/6
y = (-13/6)x + c
x = 2, y = 8
8 = (-13/6)(2) + c
c = 37/3
y = (-13/6)(6) + (37/3) = -⅔
2) y = (-13/6)x + (37/3)
3) since the slope is negative, the association between the variables is negative
