Answer:

The center is (9,4) and the radius is 6

Step-by-step explanation:

We can write the equation of a circle as

(x-h)^2 + (y-k)^2 = r^2  where (h,k) is the center and r is the radius

(x-9)^2 + (y-4)^2 = 36

(x-9)^2 + (y-4)^2 = 6^2

The center is (9,4) and the radius is 6

Answer:

Step-by-step explanation:

X^2-9^2+y^2-4^2=36

x^2-81+y^2-16=36

x^2+y^2-81-16=36

x^2+y^2-97=36

x^2+y^2=36+97

x^2+y^2=133

<u>x=</u>-\sqrt{-y^{2} +133}<u></u>

pochemuha

Answer:

23+19+27+x = 96

x > 27

not sure if the answer can be left that way or do you assume that test results are whole numbers, if so then the answer  would b=have to be 28.. but I think that >27 is the answer expected

Which of the lines graphed has a slope of -1/2 and a y-intercept of 3?
VARVARA [1.3K]

Answer:

The answer is image 3.

Step-by-step explanation:

The equation for the line will be y = (-1/2)x + 3 so the gradient is negative and you will have to find the x-intercept and y-intercept.

x-intercept :

let \: y = 0

0 =   - \frac{1}{2} x + 3

\frac{1}{2} x = 3

x = 3 \div  \frac{1}{2}

x = 6

y-intercept :

let \: x = 0

y =  -  \frac{1}{2} (0) + 3

y = 3
