Well the answer to part A would be 5/66 since its 5 people sharing a total amount of 66 pounds of flower. If you change it to a decimal it would be .08...

So your answer 5/66 or .08.. would be found between 0 and 1 because .08 is less than 1 but greater than 0

Answer:

D and F

Step-by-step explanation:

$x^{2}+4x+4=12$ can be rewritten as $x^{2} +4x-8=0$ .

From there you can use the quadratic formula $x=\frac{-b±\sqrt{b^{2}+4ac } }{2a}$ (ignore the A, I can‘t seem to remove it), where a=1, b=4, and c=-8.

$x=\frac{-4±\sqrt{4^{2}-4(1)(-8)} }{2(1)}$

Then you get $x=\frac{-4±\sqrt{16+32}}{2}$

Then you get $x=\frac{-4±\sqrt{48} }{2}$

So $x=-2±\frac{4\sqrt{3} }{2}$

Which means $x=-2+2\sqrt{3}$ or $-2-2\sqrt{3}$ which are choices D and F.

Why is this graph proportional?

Anastasy [175]

Answer:

The graph represents a linear function that passes through the origin.

Step-by-step explanation:

Proportional functions can be represented by $y=kx$ , where $k$ is some constant. They form a straight line that always pass through the origin (0,0). We can see all these characteristics in the graph, thus the graph is proportional.
