Hey There!

The formula of the general form equation is

0 = Ax + By + C

As we look at the answer choices we see that the last choice best represents the correct answer.

x + y + 2 = 0

Best matches the formula given and therefore that would be the correct answer.

Thus, the answer would be x + y + 2 = 0

What integer represents a 5-point loss added to a 2–point gain?

Hoochie [10]

Answer:

-3

Step-by-step explanation:

5 point loss is -5,

2 point gain is (+)2.

If it's added, the expression will be -5 + 2.

-5 + 2 is -3.

-3 is an integer, because integers are whole numbers and their opposites.

If this helped, please mark it brainliest.. unless there is a better answer. Thanks.

arsen [322]

Answer:

Step-by-step explanation:

20% = 20/100= 1/5

It is 1/5 of the number 150

Taking the problem what is 20% of 150

Is means equals and of means multiply

what is 20% of 150

W = 20% * 150

Change 20% to a decimal

W = .20 * 150

W = 30

The equation of circle having a diameter with endpoints (-2, 1) and (6, 7) is

densk [106]

Answer:

$(x-2)^{2}+(y-4)^{2}=25$

Step-by-step explanation:

step 1

Find the diameter of the circle

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

$A(-2,1)\\B(6,7)$

substitute the values

$d=\sqrt{(7-1)^{2}+(6+2)^{2}}$

$d=\sqrt{(6)^{2}+(8)^{2}}$

$d=\sqrt{100}$

$d=10\ units$

The radius is half the diameter

$r=10/2=5\ units$

step 2

Find the center of the circle

the center of the circle is the midpoint between the endpoints of the diameter

The center is

$(\frac{-2+6}{2},\frac{1+7}{2})$

$(2,4)$

step 3

Find the equation of the circle

The equation of the circle is

$(x-h)^{2}+(y-k)^{2}=r^{2}$

substitute the values

$(x-2)^{2}+(y-4)^{2}=5^{2}$

$(x-2)^{2}+(y-4)^{2}=25$
