The general equation of circles is (x-h)^2 + (y-k)^2 = r^2 where (h,k) is the center. 1. 2x^2+2y^2=72 =x^2+y^2=36  c: (0,0); r = 62. (x-3)^2+(y-1)^2=4 : c: (3,1); r = 23. (x-5)^2+(y+2)^2=49;  c: (5,-2); r = 74. (y-4)^2+(x-10)^2=64:  c: (4,10); r = 85.(x^2-6x+9)+(y^2+8y+16)=1:  c: (3,-4); r = 16. x^2+12x+y^2-8y=-27 =x^2+12x + 36+y^2-8y+16=-27+36+16=25:  c( -6,4); r = 5

HELP WILL GIVE 15 POINTS <br>what is the range of this function and pls explain​
Nataly [62]

Answer:

f(x)\geq -2

Step-by-step explanation:

Range corresponds to the values of y on the y-axis. If we see the graph the minimum value of the y-coordinate is -2 and then it tends to increase from it. We do not know till where the y values will increase in the figure it shows 6 but it's still actually increasing we keep on tracing the graph but the minimum value will always remain the same which is -2 . So we can say that the range of the function is

f(x)\geq -2\\

Where f(x) is the function and since the values of y on the y-axis increase from -2 we can say that the function has the range of values greater than or equal to -2

-3(-4n + 30) = -30 need help​
DIA [1.3K]

First we will do -3 times everything in the parenthesis.

-3 times -4n = 12n

-3 times 30 = -90

SO,

12n - 90 = -30

       +90    +90

12n = 60

divide 12 on both sides;

n = 5

This is your answer,

The square of a positive number is 24 more than 5 times a number. What is the value of the number?
satela [25.4K]
First, let's construct an algebraic equation to formally find the answer:

Let x represent (the value of) the unknown number. 

x²= 5x + 24 --- This equation shows that the (positive) number's square equals 24 more than 5 times the number.

Now we can solve for x (the number):

                 x² = 5x + 24
  x² - 5x - 24 = 0
(x + 3)(x - 8) = 0
                   x =  -3, 8

Therefore, this means that x (the number ) can be either -3 OR 8. Both will satisfy the description.
Hope this helps!
