Answer:

Step-by-step explanation:

The circle equation (x-a)²+(y-b)²=r² has a radius of r and a center of (a,b).

You can expand your equation from (x-5)²+y²=9 to (x-5)²+(y-0)²=3².

Using this information, you can see that a=5, b=0, and r=3.

Therefore the center is (5,0) and the radius is 3.

**This question involves circle equations, which you may want to revise. I'm always happy to help!

Answer:

Step-by-step explanation:

Because the equation can be written in the form (x-p)^2+(y-q)^2. So it represents a circle with the radius r=3 and the center of (5,0).

Answer:

$min(10,w)=\left \{ {{w} \quad\text{for } w$

Step-by-step explanation:

No value of w is given, so we can only tell you the meaning of min(10, w):

When w < 10, min(10, w) is w.

When w ≥ 10, 10 is the smaller of the two values, so min(10, w) = 10.

If x – 9 is a factor of x2 – 5x – 36, what is the other factor? x – 4 x 4 x – 6 x 6

Sergio [31]

Answer:

(x+4)

Step-by-step explanation:

Solve by factoring. Think about what numbers multiply to be -36 (the last term) BUT also subtract/add up to be -5, which is the middle term. The answer to this is 4 and -9. Therefore, the two factors are (x-9)(x+4)

Can someone help me with this

jolli1 [7]

Answer:

4 sides

Step-by-step explanation:

A lot of math is about pattern matching. Here, you're asked if sides are the same length (one side matches another), if there are right angles (square corners), and if the number of angles or sides is 4.

You might make the observations ...

pink: 2 pairs of parallel sides that are the same length (4 sides). Adjacent sides are different length.

orange: all 4 sides are congruent and at right angles

blue: 2 pairs of parallel sides that are the same length (4 sides). Adjacent sides are different length.

green: 2 pairs of parallel sides that are the same length--4 sides and 4 right angles. Adjacent sides are different length.

The only feature in common is "4 sides."

Solve x + 3y = 9 3x – 3y = -13 (1 point)

Answer:

(-1, 10/3)

x = -1

y = 10/3

Step-by-step explanation:

To solve a system, one of the methods you can use is elimination. To use elimination, you need a variable to have the same coefficient in BOTH equations. Since both equations have "3y", with the same coefficient (3), we can use this method.

We want to eliminate a variable by cancelling it out. Since positive 3y PLUS negative 3y is 0, the variable in eliminated. ADD each of the terms in the equations together.

. x + 3y = 9

+ 3x – 3y = -13

. 4x – 0y = -4 3y - 3y = 0

. 4x = -4 Divide both sides by 4 to isolate 'x'

. x = -1 Solved for the x-coordinate

Since we know one variable, 'x', we can easily find the other, 'y'. Substitute 'x' with -1 in any of the equations. Then, isolate 'x'.

x + 3y = 9

(-1) + 3y = 9

-1 + 1 + 3y = 9 + 1 Add 1 to both sides to cancel out left side.

3y = 9 + 1 Add on the right side (9 + 1 = 10)

3y = 10 Divide both sides by 3 to isolate 'y'

y = 10/3 Solved for the y-coordinate

Put the 'x' and 'y' coordinates together in an ordered pair, which you write as (x, y).

The solution to the system is (-1, 10/3).
