Answer: B) (x-1)2+(y+1)2= 25 radius = 5 miles

Step-by-step explanation:

In order to get this answer you see that you are adding a negative to x in the first part then multiplying it by 2. Second, you add y+1 then multiplying it by 2. You get the radius of 25 which equals 5 miles. Look at the graph to also check your answers to the problem.

Answer:

B) (x-1)2+(y+1)2= 25 radius = 5 miles

Step-by-step explanation:

Equation of a circle:

(x - h)² + (y - k)² = r²

(h,k) = (1, -1)

r = 5

(x - 1)² + (y - -1)² = 5²

(x - 1)² + (y + 1)² = 25

dmitriy555 [2]

Following are calculation to the given eqution:

Given:

$\bold{(-m^2+6)+(-4m^2+7m+2)}$

To find:

Solve the equation.

Solution:

$\to \bold{(-m^2+6)+(-4m^2+7m+2)}\\\\\to \bold{-m^2+6-4m^2+7m+2}\\\\\to \bold{-5m^2+7m+8}\\\\\to \bold{-1(5m^2-7m-8)}\\\\$

Therefore, the final solution is " $-1(5 m^2-7m-8)$ ".

For a diamond problem what two numbers' sums equal 31 and their product is 234?

s344n2d4d5 [400]

Let

x-------> the first number

y------> the second number

we know that

$x+y=31$

$x=31-y$

equation $1$

$x*y=234$

equation $2$

substitute equation 1 in equation 2

$(31-y)*y=234\\ 31y-y^{2} =234\\ -y^{2} +31y-234=0$

using a graph tool-----> to resolve the second order equation

see the attached figure

the solution is

$13 and 18$

Solve for |2x + 4|-1=7

Rudik [331]

Answer:

x = - 6 or x = 2

Step-by-step explanation:

The absolute value function always returns a positive value. However, the expression inside can be positive or negative.

Given

| 2x + 4 | - 1 = 7 ( add 1 to both sides )

| 2x + 4 | = 8, thus

2x + 4 = 8 ( subtract 4 from both sides )

2x = 4 ( divide both sides by 2 )

x = 2

OR

-(2x + 4) = 8

- 2x - 4 = 8 ( add 4 to both sides )

- 2x = 12 ( divide both sides by - 2 )

x = - 6

As a check

Substitute these values into the left side of the equation and if equal to the right side then they are the solutions.

x = 2 → | 4 + 4 | - 1 = | 8 | - 1 = 8 - 1 = 7 ← True

x = - 6 → | - 12 + 4 | - 1 = | - 8 | - 1 = 8 - 1 = 7 ← True

Hence the solutions are x = - 6 or x = 2
