vetex is (h,k)

so
1/2(x-7)^2=y+4
times 2 both sides
(x-7)^2=2(y+4)
(x-7)^2=4(1/2)(y-(-4))
vertex is (7,-4)

Cecilia's mom ordered pizza for dinner. The pizza has two slices of pepperoni, two slices of mushroom, and two slices of anchovy
Alborosie

Answer:

If the first slice is pepperoni, then we have left:

1 slice of pepperoni.

2 slices of mushrooms.

2 slices of anchovy.

Then the possible combinations are:

Pepperoni and pepperoni (in only one combination)

Pepperoni and mushrooms (in two combinations, because there are two slices left)

Pepperoni and anchovy (Again in two combinations, because there are two slices left)

These are the 3 possible combinations, 5 in total.

Maru [420]

Answer:

(B)x=48^\circ

Step-by-step explanation:

The diagram has been drawn and attached below.

From the diagram

52^\circ+y+59^\circ=180^\circ$ (Linear Postulate)\\y=180^\circ-(52^\circ+59^\circ)\\y=69^\circ

Also:

x+y+63^\circ=180^\circ$ (Sum of angles in a triangle)\\x+69^\circ+63^\circ=180^\circ\\x=180^\circ-(69^\circ+63^\circ)\\x=48^\circ

The value of x is 48 degrees.
