Answer: 133/2π

Step-by-step explanation:

Area of ends:

Area of Circle = πr²

π3.5²=49/4π

There are two ends so you multiply that by 2 to get 49/2π

Area of Rest:

First, you need to find the circumference using the equation: πd

πx7=7π

Then to find the area you just need to multiply 7π by the height

7π x 6 = 42π

Total surface area

You now just need to add them together

49/2π + 42π = 133/2π

Which graph best represents -5y = -6x + 15

frutty [35]

Answer: Option c.

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

$y=mx+b$

Where "m" is the slope and "b" is the y-intercept.

Given the equation:

$-5y = -6x + 15$

Solve for "y" in order to write in Slope-Intercept form:

$y = \frac{-6}{-5}x + \frac{15}{-5}\\\\y = \frac{6}{5}x -3$

Now you can identify that that the slope and the y-intercept are:

$m=\frac{6}{5}\\\\b=-3$

A posive slope means that the the line moves upward from left to right.

With this information, you can conclude that the the graph that best represents the given equation is the graph shown in the Option c.
