If u are referring to explaining how to solve the circumference of circle,To calculate the circumference of a circle, multiply the diameter of the circle with π (pi). The circumference can also be calculated by multiplying 2×radius with pi (π=3.14). or in other words, The formula for the circumference of a circle is C = 2πr, where r is the radius. to find the radius, u must find the diameter and divide that number by 2. from there is would be 2 times r(radius) times pi

Solve the system of equations graphicallySolution=?

BigorU [14]

The given system is

$\begin{cases}y=\frac{5}{2}x-8 \\ y=-\frac{1}{2}x-2\end{cases}$

Given that y = y, let's combine the equations

$\frac{5}{2}x-8=-\frac{1}{2}x-2$

Let's solve for x

$\begin{gathered} \frac{5}{2}x+\frac{1}{2}x=8-2 \\ \frac{6}{2}x=6 \\ 3x=6 \\ x=\frac{6}{3} \\ x=2 \end{gathered}$

Then, we find y

$y=-\frac{1}{2}x-2=-\frac{1}{2}\cdot2-2=-1-2=-3$

The solution is (2, -3).

The image below shows the solution graphically.

5-7y/2+4y equals -8/7

Ksenya-84 [330]

Answer:

$\boxed{y = 3}$

Step-by-step explanation:

$= > \frac{5 - 7y}{2 + 4y} = - \frac{8}{7} \\ \\ = > 7(5 - 7y) = - 8(2 + 4y) \\ \\ = > (7 \times 5) - (7 \times 7y) = ( - 8 \times 2) + ( - 8 \times 4y) \\ \\ = > 35 - 49y = - 16 - 32y \\ \\ = > 35 - 49y + 32y = - 16 \\ \\ = > 35 - 17y = - 16 \\ \\ = - 17y = - 16 - 35 \\ \\ = > \cancel{- }17y = \cancel{- } 51 \\ \\ = > 17y = 51 \\ \\ = > y = \frac{51}{17} \\ \\ = > y = 3$
