Change these equations into the equations of linear functions.
\left \{ {{4x-2y=22} \atop {6x+9y=-3}} \right. \\ \\
 \left \{ {{-2y=-4x+22} \atop {9y=-6x-3}} \right. \\ \\
 \left \{ {{y=2x-11} \atop {y=-\frac{2}{3}x-\frac{1}{3}}} \right.

Draw function graphs and read coordinates of the intersection.
\left \{ {{x=4} \atop {y=-3}} \right.

Which statement is true about the function f(x)= -x?
rosijanka [135]

Answer:

The domain of the graph is all real numbers less than or equal to 0.

Step-by-step explanation:

Hello,

We know that we cannot take square root of negative numbers, so we must have

-x\geq 0 \ \text{ ***multiply by -1, it changes the inequality, so*** } \\ \\\large \boxed{\sf \ \ x\leq0 \ \ }

So the domain of the graph is all real numbers less than or equal to 0.

For information, I attached the graph so that we can verify it.

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

35,000,000 in scientific notation
Mandarinka [93]

Answer:

3.5 times 10^7

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

3.5×10^7
