3 0

Answer:

D

Step-by-step explanation:

Finding y int by substituting the points given (say y int is x)

(-9) = 4(-4) + x

(-9) = -16 + x

x = 7

With the y int, you can now write the equation

y = -4x + 7

Describe at least two differences between constructing an inscribed regular hexagon and constructing an inscribed square.
liberstina [14]

Correct answer is A.

The diameter of the circle is used for the square construction, but the radius of the circle is used for the regular hexagon construction.

<h3>How to calculate the diameter?</h3>

If you know the radius of the circle, multiply by 2 to get the diameter. The radius is the distance from the center of the circle to the edge. For example, if the radius of a circle is 4 cm, then the diameter is 4 cm x 2 = 8 cm. If you know the circumference of the circle, divide by π to get the diameter.

<h3>Briefing:</h3>

The diameter of the circle is used for the square construction, but the radius of the circle is used for the regular hexagon construction which is A.

The diameter of the circle is used for the square as l=2r therefore corresponds to the diameter, while for a hexagon r=r being the radius of the circle.

Bob installed new windows in his house which were advertised to cut his energy bill by 7.1% per month after installation. If his
maxonik [38]

His monthly bill before he installed the new windows was $339.074...

<u><em>Explanation</em></u>

Suppose, his monthly bill before he installed the new windows was  x dollar.

As his energy bill was decreased by 7.1% per month after installation, so <u>the amount of bill decreased</u> =x*\frac{7.1}{100}=0.071x dollar

Given that, his new energy bill was $315. So the equation will be...

x-0.071x= 315\\ \\ 0.929x=315\\ \\ x=\frac{315}{0.929}=339.074....

So, his monthly bill before he installed the new windows was $339.074...
