Answer: (x-4)^2+(y+9)^2=10^2

Explanation: The circle in the problem takes the form (x-h)^2+ (y-k)^2=r^2. The hiker started at the center of the circle (h,k) = (4,9). The radius of the circle= 12. When you plug these values in you get (x-4)^2+ ky+9)^2=10^2

Seven times the smaller
Taya2010 [7]

Given:

Seven times the smaller  of two consecutive even  integers  is the same as  -300 minus 4 times the  larger integer.

To find:

The integers .

Solution:

Let the smaller even integer be x.

So, larger even integer is x+2 because they are consecutive even  integers.

Seven times the smaller  integer = 7x

-300 minus 4 times the  larger integer = -300-4(x+2)

Now,

7x=-300-4(x+2)

7x=-300-4x-8

7x+4x=-308

11x=-308

Divide both sides by 11.

x=\dfrac{-308}{11}

x=-28

So, the smaller even integer is -28.

x+2=-28+2=-26

So, the larger even integer is -26.

What’s the answer and how did you get it? i’m confused
Sidana [21]

Answer:

The answer is 3.

Step-by-step explanation:

Because you should put the gh with gh, 2  is equivalent to 2 (so the 2 disappeared) and you only have 8-7=1 plus 2=3.
