The equation of a circle is given below. What is its center?

svp [43]

Answer:

$( \frac{2}{3}, 0)$

Step-by-step explanation:

The general equation for a circle is

${(x - a) }^{2} + {(y - b) }^{2} = {r}^{2}$

Where a and b are the x and y values of the centre. So comparing to your equation you can see that a is 2/3 and b is 0

5/2x - 1.5 = 3.5 what is the value of x

azamat

Answer:

Step-by-step explanation:

Add 1.5 to both sides:

5/2x-1.5+1.5=3.5+1.5

5/2x=5

Multiply both sides by 2/5

(2/5)*(5/2x)=(2/5)*(5)

mr. Smith has twice as much money as mr. hairy the average amount of money they have is $489 how much money does mr. Smith have

Darya [45]

Ok, so this one requires you to set up an equation that makes sense....(mr. Smith + mr. Harry)/2= 489...that is the average money from the problem....ok so let’s add some variables now and make it look like math. 2x is mr smith from the first sentence. X is mr. Harry. This yields

(2x+x)/2=489.....use inverse operations to yield
2x+x=978

Combine like terms to get

3x=978

Then divide by 3
To give you x=326

What does x tell you?
X= harry = 326
2x = Smith = 652

To check add them together and divide by 2 to get the average....489
