If n is the first integer, then n+2 is the second one. The equation for the sum can be written as
  n + (n+2) = 24 . . . . . . this equation can be used to solve the problem

  2n = 22 . . . . . . . . . . . simplify, subtract 2
  n = 11

The integers are 11 and 13.

_____
I like to solve problems like this by looking at the average of the integers. Here, it is 24/2 = 12. The consecutive odd integers whose average is 12 are 11 and 13.

Is x - 8 a factor of the function f(x) = -2x3 + 17x2 - 64? Explain.
Oduvanchick [21]

we know that

If (x-8) is a factor of the function f(x)=-2x^{3}+17x^{2}-64

then

x=8 is a root of the function f(x)

therefore

For x=8 the value of the function must be zero

Verify

Substitute the value of x=8 in the function

f(8)=-2(8)^{3}+17(8)^{2}-64

f(8)=-2(512)+17(64)-64

f(8)=-1,024+1,088-64

f(8)=-1,088+1,088

f(8)=0

therefore

<u>the answer is</u>

Yes, (x-8) is a factor of the function f(x)

Answer:

(x-5)^2+(y-2)^2=9\\

Step-by-step explanation:

So, you basically want the equation of the circle.

Given:

Center(C): C(5, 2)

r=3

The equation of circle is:

(x-h)^2+(y-k)^2=r^2\\

Where, (h, k) represents the center point and r is the radius of the circle.

Plotting the values in the equation:

(x-5)^2+(y-2)^2=3^2\\

(x-5)^2+(y-2)^2=9\\

This is the equation of the circle of center (5, 2) and radius 3.
