Answer:

x^2 + y^2 +16x - 24y +159 = 0

Rearrange:

x^2 +16x + y^2 - 24y = -159

(16x/2)^2 = 64

(-24y/2)^2 = 144

x^2 + 16x + 64 + y^2 - 24y + 144 = -159 + 144 + 64

x^2 + 16x + 64 + y^2 - 24y + 144 = 49

Reduce the trinomials to binomials:

(x + 8)^2 + (y - 12)^2 = 49

Thus the center point is (-8, 12) and the radius is 7

What is the nth term rule of the linear sequence below?<br><br> 6, 13, 20, 27, 34, . . .
nignag [31]

Answer:

7n - 1

Step-by-step explanation:

notice that the difference between adjacent terms is 7.

so nth term is given by:

nth term = first term + (n-1)×difference (n is any number)

= 6 + (n-1)7

= 6+ 7n -7

= 7n - 1

hope this helps :-))

If f(x) is a linear function, which statement must be true?
Harlamova29_29 [7]

The statements look all false:

  • A linear function can have constant terms, which is the b coefficient in the expression y=mx+b. For example, y=3x+5 has a constant term 5
  • A linear function has a x term. In the same example as before, 3x is the x term
  • The coefficients can be different from 1. In the example before, the x coefficient is 3 and the constant term is 5.
  • This looks like option b. Maybe there was a typo, and either b or d must be true.
