PLEASE I NEED THIS NO which of the following equations is equivalent to y= - 1/2x^2 + 4 x + c (1/2 is a fraction )
a. y= -1/2 (x+4)^2+ c - 8
b. y= -1/2 (x+2)^2+ c - 16
c. y= -1/2 (x-4)^2+ c + 4
d. y= -1/2 (x-4)^2+ c+ 8

i am thinking c. sorry if im wrong .

step-by-step explanation:

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
