Answer: 3\frac{7}{8}

<u>Convert</u>

-1/8+2/5=11/40

<u>Convert 3 3/5 into an Improper Fraction</u>

Multiply 3×5 and get 15. Now add 3 and get 18.

3 3/5 = 18/5

<u>Add</u>

11/40+18/5=31/8

<u>Convert your answer into a Mixed Number</u>

<u></u>31/8=3\frac{7}{8}<u></u>

The general form of the equation of a circle is x2+y2−4x−8y−5=0.
ludmilkaskok [199]
The general equation of a circle is (x-a)^{2} + ( y-b)^{2} =  r^{2} where a and b are the x and y components of the center respectively. 

In order to get into this format, we have to use a method that I'm drawing a blank on the same, my apologies about that.

Anyway, what you want is to first isolate the variable on side so now you have: x^{2} - 4x +  y^{2} - 8y = 5 (you'll see why I rearranged this soon)

Now you have to make it into an equation that can be simplified into the format stated earlier.

So, You have to take the x & y terms (-4x & -8y in this case) divide them each by two, and then square them.

The result of this step is the equation: x^{2} -4x + 4 +  y^{2} - 8y + 16 = 5 + 4 + 16 
Notice the new components that have been added (4 & 16) and how the have been added to both sides. That is an important step.

Now we simplify and get: (x-2)^{2} +  (y-4)^{2}  = 25

So the coordinate of the center is: (2,4) and the radius is 5

-8m - 12 &gt; -5(m - 8) – 3(m - 7)<br> Write the solution to the inequality
horrorfan [7]

Answer:

No answer.

Step-by-step explanation:

- 8m - 12 > -5m + 40 - 3m + 21

combine terms

-8m - 12 > -8m +61

add 8m to both sides

-12 > 61

negative 12 is not greater than 61

What value of y makes the equation 4x – 3y = 17 true, when x = 2?
earnstyle [38]

Answer:

y = -3

Step-by-step explanation:

4x – 3y = 17

x = 2

4(2) - 3y = 17

8 - 3y = 17

-3y = 9

y = -3
