Standard equation for a circle is: (x -h)² + (y - k)² = r²
(h,k) is the center which is given to be: (0,0) so you just need the radius.
The radius is the distance from the center to the point (-4,5) on the edge.

Use the distance formula

d = √[(-4 - 0)² + (5 -0)²]
d = √[16 + 25]
d = √[41]

radius is √[41]
so the equation for the circle is: x² + y² = 41

Tom mowed lawns for the summer. In June he deposited $120 the first week, $80 the second week, and $75 the following week. Then

melisa1 [442]

So, let's add up the total amount he made:
120 + 80 + 75 = 275
If he withdrew $30:
275 - 30 = 245
Tom will have $245 at the end of June

Rudy, Maria, and Tito have a total of x textbooks Rudy has 6 textbooks andTito and Maria each have y textbooks. How many textboo

shtirl [24]

Answer:

Tito have $\frac{x-6}{2}$ textbooks in terms of x

Step-by-step explanation:

Rudy has 6 textbooks

We are given that Tito and Maria each have y textbooks

So, Tito has no. of books = y

Maria has no. of books = y

So, total number of textbooks = 6+y+y=6+2y

We are given that Rudy, Maria, and Tito have a total of x textbooks

So,6+2y=x

So, 2y=x-6

$y=\frac{x-6}{2}$

Hence Tito have $\frac{x-6}{2}$ textbooks in terms of x
