Which of the following is a result of shifting a circle with equation (x + 3)2 + (y - 2)2 = 36 right 3 units?A. The y-coordinate of the center of the circle decreases by 3.
B. The y-coordinate of the center of the circle increases by 3.
C. The x-coordinate of the center of the circle increases by 3.
D. Both the x- and y-coordinates of the center of the circle increase by 3.

Answers

Answer 1

Answer:

Answer:

Option C is correct that is the x-coordinate of the center of the circle increases by 3.

Step-by-step explanation:

The given equation is:

$(x+3)^2+(y-2)^2=36$

Since, the circle is shifted right 3 units

There, will be no change in y-axis because it is horizontal change.

So, Option A,B and D are discarded.

Therefore, Option C is correct that is the x-coordinate of the center of the circle increases by 3.

10x -2y = 10 in slope intercept form

Answers

slope-intercept form: y = mx + b
the point is to get y alone on one side of the equation:

10x - 2y = 10
-10x -10x
-2y = -10x + 10
-2y/-2 = -10x/-2 + 10/-2
y = 5x - 5

Solve by factoring.. m^2 + 8m + 7 = 0

Answers

In order to solve an equation by factoring, it should be that the equation is equal to zero.
m^2 + 8m + 7 = 0
For this case we have, to do completing the square in order to factor this equation.

m^2 + 8m = -7
m^2 + 8m + 16 = -7 +16
(m+4) (m+4) = 9
(m+4)^2 = 9

Take the square root of both sides,
m+4 = 3
m = -1

Is 4/8 greater or less than 3/4

Answers

Less than because 1/2 is smaller than 3/4

4/8 simplifies to 1/2, and 1/2 is 0.5.

3/4 as a decimal is 0.75.

0.5 is less than 0.75, so 4/8 is less than 3/4.

What value of x makes the equation true? PLZ HELP RIGHT THANK YOU

–7.12 = –4.8 + x

A.

–11.92

B.

–11.2

C.

–2.32

D.

2.32

Answers

so just remember tha tyou can do anything to an equation as long as you do it to both sides (except divide by 0) so
-7.12=-4.8+x
add 4.8 to both sides since -4.8+4.8=0 so it cancels
4.8-7.12=x
simplify
4.80-7.12=-2.32
-2.32=x
the naswer is C

-7.12 = -4.8 + x

-7.12 = x - 4.8

Add 4.8 on both sides

x = -7.12 + 4.8

x = -2.32

Your final answer is C. -2.32.

when you integrate x^n the result is (x^n+1)/n+1 +C
where n is the old power so the result will be (C)
