Acollege student needs 11 classes that are worth a total of 40 credits in order to complete her degree. the college offers both 4-credit classes and 3-credit classes. which system of equations can be used to determine f, the number of 4-credit classes the student can take to complete her degree, and h, the number of 3-credit classes?

f.) f + h = 40
4h + 3f = 11

h.) f + h = 40
4f + 3h = 11

g.) f + h = 11
4h + 3f = 40

j.) f + h = 11
4f + 3h = 40

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
