Answer:

X=0

Step-by-step explanation:

Frst we want to check is it symmetry function?

F(-x)=f(x)?

We know that f(x)=x^2+0x-4=x^2-4.

What about f(-x)? F(-x)=(-x)^2-4=x^2-4, so we can conclud that f(-x)=f(x), the summetry!

Intesections with x is in the -2 and 2, so the middle is x=0.

On the checkerboard, 4/10 of the pieces left are red. What fraction of the pieces left are black? Write the equation.

Alexeev081 [22]

Answer:

The fraction of black pieces left is $\frac{6}{10}$

Step-by-step explanation:

Given as :

On the checkerboard , The fraction of red pieces left = $\frac{4}{10}$

Let The fraction of black pieces left = x

So, The fraction of black pieces left = x = 1 - $\frac{4}{10}$

Or, x = $\frac{10-4}{10}$

Or, x = $\frac{6}{10}$

Hence The fraction of black pieces left is $\frac{6}{10}$ Answer

$3 - \frac{2}{3} = 2 \frac{1}{3}$

$4 + \frac{2}{5} = 4 \frac{2}{5}$

$5 \div \frac{4}{7} = 8 \frac{3}{4}$

$\frac{4}{5} \times \frac{2}{3 } = \frac{8}{15}$

$\frac{1}{3} \div \frac{3}{5} = \frac{5}{9}$
