hello :
the quadratic function is :
<span> f(x) = a(x-1)(x+1)
but ; f(0) = -6</span>
a(0-1)(0+1) = -6
-a = -6
a=6
<span>the equation is : 6(x-1)(x+1) = 0</span>
The Correct choice among them is ~ B
because it's a equation !
I can't understand your question do you have any number there?
Answer:
y=1/5x-31/5 (or y=0.2x-6.2 in decimals)
Step-by-step explanation:
x=5y-8 (original equation)
x+8=5y <u>(Addition Property of Equality)</u>
1/5x+8/5=y <u>(Division Property of Equality, </u><u>slope </u><u>of </u><u><em>original equation </em></u><u>is </u><u>1/5</u><u>)</u>
<u />
y-y1=m(x-x1) <u>(point-slope formula)</u>
y-(-5))=1/5(x-(6)) <u>(plug in the slope that was found earlier and the point given in the question)</u>
y+5=1/5(x-6)
y+5=1/5x-6/5 (Distributive Property of Multiplication) Note: 5 = 25/5
<u>y=1/5x-31/5</u> (Subtraction Property of Equality, and there's your answer)
<u>y=0.2x-6.2</u><em> </em>(This is the same answer, but written with decimals)
There wasn't much to go off of but based of the information you've gave me the answer would be 7.68=6.28
