5. Which best describes the graph of y >x^2 +6x+ 12? A. The vertex is at (-3,3). The parabola is a dotted line that opens up. Shading is above the parabola.

B. The vertex is at (-3,3). The parabola is a solid line that opens up. Shading is below the parabola.

C. The vertex is at (3, 3). The parabola is a dotted line that opens down. Shading is above the parabola.

D. The vertex is at (-3, 3). The parabola is a solid line that opens up. Shading is above the parabola.

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)

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.

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.
