Answer:

center (-3, 0)
radius 4

Step-by-step explanation:

The standard form equation of a circle is ...

(x -h)^2 +(y -k)^2 = r^2 . . . . . . . . . center at (h, k), radius r

Divide your given equation by 2 to put it into standard form:

(x +3)^2 +y^2 = 16

Comparing to the above, we see ...

h = -3
k = 0
r = √16 = 4

The center point of the circle is (-3, 0); the radius is 4 units long.

What is the equation for the values in the table

devlian [24]

Step-by-step explanation:

Taking any two points through which the line passes;(-10,-3) and (-5,-1)

The equation of the line is given by

$\frac{y2 - y1}{x2 - x1} = \frac{y - y1}{x - x1}$

$=> \frac{ - 1 - ( - 3)}{ - 5 - ( - 10)} = \frac{y - ( - 3)}{x - ( - 10)} = \frac{y + 3}{x + 10}$

$=> \frac{ - 1 + 3}{ - 5 + 10} = \frac{y + 3}{x + 10}$

$=> \frac{2}{5} = \frac{y + 3}{x + 10}$

$=> 5(y + 3) = 2(x + 10)$

=> 5y+15 = 2x+20

=> 5y =2x+5

$=> y= \frac{2}{5} x + 1$

What is the polynomial of 3,4

Sav [38]

The degree of a polynomial is the highest power of x in its expression. Constant (non-zero) polynomials, linear polynomials, quadratics, cubics and quartics are polynomials of degree 0, 1, 2 , 3 and 4 respectively. The function f(x)=0 is also a polynomial, but we say that its degree is 'undefined'.

stich3 [128]

Answer: -4/5

Step-by-step explanation:

you can use slope formula to solve this question. （Y1-Y2）/（X1-X2）. So the answer to this question should be （0-4）/（5-0）= -4/5

The temperature on the side of a space shuttle that faces the sun is +250°C. The temperature on the shaded side is -130°C. What

Evgesh-ka [11]

Answer:

380º

Step-by-step explanation:

Since the shaded side is in the negative and the sun side is positive and you're trying to find the difference between them, first you try to get the negative number to be positive. So add 130 to -130 to get 0. Then add another 250º to equal the two amounts. Now since they are equal, add the numbers that you used to get the two numbers to be the same: 130+250 = 380
