Answer:

Step-by-step explanation:

When there is a number subtract a negative number then you add the two numbers. For example in this case, the question is 3-(-3). The negative sign for the -3 will cancel out with the minus sign giving you 3+3. Then, the answer is 6. Another example would be 5-(-6). The minus sign cancels out the negative sign from -6 giving you 5+6. The answer is 11 in this case.

If the circumference of a circle is changed from 9 cm to 3 cm, how will the diameter change?

klemol [59]

Answer:

If the circumference of a circle is changed from 9 cm to 3 cm, then the diameter decreases by a factor of 3.

Solution:

Given, the circumference of a circle is changed from 9 cm to 3 cm,

We have to find how will the diameter change from the given equations?

We know that, diameter = 2 $\times$ radius and circumference = 2π $\times$ radius.

$\text { Now, circumference }=\pi \times(2 \times \text { radius }) \rightarrow \text { circumference }=\pi \times \text { diameter }$

$\text { At initial stage } \rightarrow \text { circumference }=9 \rightarrow \pi \times \text { diameter }=9 \rightarrow \text { diameter }=\frac{9}{\pi}$

$\text { Now, after change } \rightarrow \text { circumference }=3 \rightarrow \pi \times \text { diameter }=3 \rightarrow \text { diameter }=\frac{3}{\pi}$

$\text { Now, for finding change in factor }=\frac{\text { new diameter }}{\text { old diameter }}=\frac{\frac{3}{\pi}}{\frac{9}{\pi}}=\frac{3}{9}=\frac{1}{3}$

Hence, the diameter decreases by a factor of 3.

How can you describe the graph of the equation ax + by = c? Explain

scoundrel [369]

Answer:

When A and B are not both zero, the graph of Ax + By = C is always a line. The graph of Ax + By = C, where A and B are not both zero, is a line. Divide both sides by B. Because the form Ax + By = C can describe any line, it is called the standard form of an equation for a line.

Hope this helps you!
