Answer:
couted by 10
Step-by-step explanation:
Answer:
14: 1
Step-by-step explanation:
<em>Cross multiply:</em>
3(2a -3b)= 5(a +b)
<em>Expand:</em>
6a -9b= 5a +5b
<em>Move all a terms to one side, b terms to the other:</em>
6a -5a= 9b +5b
<em>Simplify:</em>
a= 14b
<em>Divide by b on both sides:</em>
<em>Rewriting 14 as a fraction:</em>
∴ a: b= 14: 1
F(x) = -(x2+x-72)
y = -(x - 8)(x + 9)
the solutions are x = 8, -9; so the parabola is upside down (umbrella) crossing the x at 8 and -9, meaning that -9 + 8 = -1/2 = -0.5 is where the focus is, or x = -0.5 as the axis of symmetry
Answer:
