F(2) means that you are plugging in 2 for x, while f(x)=2 means that the equation equals 2 (y=2) at a certain x value.

Answer:

$- 23$

Step-by-step explanation:

$24 \div {2}^{2} ( - 3) - 7 - {2}^{2} - 2(3 - 6) \\ 24 \div {2}^{2} ( - 3) - 7 - {2}^{2} - 2( - 3) \\ 24 \div 4( - 3) - 7 - 4 - 2( - 3)\\ 6(-3) - 7 - 4 -2(- 3) \\ - 18 - 7 - 4 + 6 \\ -25 -4 +6 \\ -29 +6 \\ - 23$

Which fraction and equivalent decimal correctly shows the ratio of shaded circles to all circles?

sergeinik [125]

Shaded circles = 4
Total circles = 12

$\frac{shaded~circles}{total~circles}$ = $\frac{4}{12}$

$\frac{4}{12}$ as a simplified expression = $\frac{2}{6}$
We can simplify it even more = $\frac{1}{3}$

Fraction = $\frac{1}{3}$

Equivalent decimal = 1 ÷ 3 = 0.33
