Answer:

Center: (-7, -4)

radius = 4

Explanation:

  • Equation: (x + 7)² + (y + 4)² = 16

Circle formula:

  • (x - h)² + (y - k)² = r²

(h, k) denotes the center of the circle, "r is radius"

Rewrite the following equation in standard form:

  • (x - (-7))² + (y - (-4))² = 4²

From this identify:

  • h = -7, k = -4, radius = 4

General equation

(x-h)²+(y-k)²=r²

So

  • (x+7)²+(y+4)²=16
  • (x+7)²+(y+4)²=4²

Center=(-7,-4)

Radius=4

What is the value of the expression “two less than six times the difference of a number and five” when n = 9?
Finger [1]

Answer:

Try solving 6(n-5)-2.

Step-by-step explanation:

I believe this can be set up as 6(n-5)-2. The difference of a number and five can be represented by n-5. If this needs to be multiplied by 6 (hence 6 times), it would become 6(n-5). Two less than that is represented by -2. Thus, two less than six times the difference of a number and five is 6(n-5) -2, which, when n=9 is plugged in, looks like 6(9-5) -2. Follow PEMDAS from there.

Emma says the GCF of 16 and 12 is 48. Her friend grace says the answer is right. Who is right? Explain help me plz
Lilit [14]
The GCF is only 12 because 16 can't multiply a number that gives you 48 only 12.

Alright, so we plug (-2) in for x. (-2)^2 =4, and we can plug that in as 4(4)+(-2)+5. Next, 4*4=16, so we get 15+(-2)+5. After that, we get 15-2+5=18

Suppose y is a positive integer.If x-(-y)=z will z be greater than x ?
alexira [117]

Answer:

Yes, <em>z</em> will be greater than <em>x.</em>

Step-by-step explanation:

Given expression is x- (-y)=z \ for \ y \ is \ a \ positive \ integer.

now let <em>y = 2 </em>and <em>x = 1</em>

Then, x- (-y)=z \\1+2 = 3 \\\\

where z> x i.e. <em>3 > 1</em>

on simplifying the given  expression in terms of y

y=z-x

now suppose if <em>x = 7 and z=3 </em>then,

y = (z-x) = (3-7) = (-4)

which gives value of y in terms of negative integer which is not possible according to the given statement since y is a positive integer. Therefore, if y is a positive integer then  z will be greater than x.
