Which of the following could be the equation for a parabola that opens down with vertex (-11, -28)?
O A. y = 5(x+28)2 - 11
O B. y = -5(x +11)2 - 28
O C. X = -5(y +28)2 - 11
Ô D. x = 5(y +11? - 28

the answer will be the last one

you bought 31 v bucks

step-by-step explanation:

25+6=31

b

step-by-step explanation:

1) the property is   ixi = a ⇔x = a   o x = -a

4(x-5)+3= 15⇒4x-20+3 = 15⇒4x-17= 15⇒4x = 15+17⇒4x = 32⇒x =32/4= 8

4(x-5) +3= -15⇒4x-20 +3 = -15⇒4x-17= -15⇒4x =-15+17⇒4x = 2⇒x =2/4= 1/2

the values are x =8 and x = 0,5
