Will give brainiest what is the a-value of the function, then determine if the graph opening up or down f(x)=−5(x+7)2+6? question 4 options: a = -5, opens down a = -5, opens up a = 7, opens up a = 7, opens down

I believe it would be A= 7, opens down.

Sorry if this is wrong.

Hope this helps ;}

step-by-step explanation:

6.48/4 4 goes into 6.48 1.62 times

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
