If the value of a in the quadratic function f(x) = ax^2+bx+c is 1/2 the function will: open down and have a minimum open up and have a maximum
open down and have a maximum
open up and have a minimum

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.

hey there! : )

4y < -4

we need to isolate y. we can do this by simply dividing both sides by 4.

4y ÷ 4 > -4 ÷ 4

simplify.

y > -1

5 - y > 0

once again, we need to isolate y, so we can start off by subtracting 5 from both sides.

5 - y - 5 > 0 - 5

simplify.

-y > -5

divide both sides by -1.

** remember that when dividing any side by a negative, you must switch the sign! **

-y ÷ -1 < -5 ÷ -1

simplify.

y < 5
