5 0

Answer:

  • center (1, 0)
  • radius 6

Step-by-step explanation:

<u>Given</u>

  (x -1)^2 +y^2 = 36

<u>Find</u>

  the circle's center and radius

<u>Solution</u>

Compare the given equation to the standard form equation for a circle.

  (x -h)^2 +(y -k)^2 = r^2 . . . . . . centered at (h, k) with radius r

This tells you ...

  • h = 1
  • k = 0
  • r = √36 = 6

Your circle is centered at (1, 0) and has a radius of 6.

If 2(6 + 3x) + 1 = - 5 + 3(x - 1), what is the value of x?
Stels [109]

Answer: x = -7

Step-by-step explanation:

2(6 + 3x) + 1 = - 5 + 3(x - 1)

(2) (6) + (2) (3x) + 1 = -5 + (3) (x) + (3) (-1)

12 + 6x + 1 = - 5 + 3x + - 1

( 6x ) + ( 12 - 1 ) = ( 3x ) + ( -5 + -3 )

6x + 13 = 3x - 8

6x + 13 - 3x = 3x - 8 - 3x

3x + 13 = -8

3x + 13 - 13 = -8 - 13

3x = -21

3x/3 -21/3

X = -7

The sum of two numbers is 30. The difference of twice the larger number and three times the smaller number is 5. What is the pos
natali 33 [55]
Let’s give these two numbers variables
Let ‘a’ be the larger number
Let ‘b’ be the smaller number

Now from the question we know:
a + b = 30 or a = 30 - b
2a - 3b = 5

Now, let’s plug the first equation into the second to find ‘b’:

2(30 - b) - 3b = 5
60 - 2b - 3b = 5
60 - 5b = 5
55 = 5b
b = 11

Now we solve for ‘a’:
a = 30 - b
a = 30 - 11
a = 19

Now the question asks for the positive difference between the two numbers, so:
a - b = ?
19 - 11 = 8

Hope this helps!
