Using the speed - distance relationship, the distance traveled by Joanne would be 55.714 km
Kuzi's speed :
- <em>16</em><em>/</em><em>2</em><em> </em><em>=</em><em> </em><em>8km</em><em> </em><em>/</em><em> </em><em>hr</em><em> </em>
Joanne's speed :
- <em>6km</em><em>/</em><em>hr</em><em> </em>
Let time taken = <em>t</em>
<u>Total</u><u> </u><u>distance</u><u> </u><u>traveled</u><u> </u><u>:</u>
8t + 6t = 130
14t = 130
t = 130/14
t = 9.2857142 hours
<u>Therefore, distance traveled by Joanne</u> :
Joanne's speed × time
6 km × 9.2857142 = 55.714 km
Therefore, distance traveled by Joanne will be 55.714 km

Simplify g(x) into 3(x^2+4+3) then move the x's to one side solve it as a two-step equation.
First one is three i think
a) A line can intersect a parabola at 2 points, 1 point, or no points respectively. The only possible way at which it intersects at 1 point, would be if it were tangent to the parabola. [Check first attachment]
b) Two different parabolas can intersect at 2 points, 1 point or no points respectively. [Check second attachment]
It is possible for 2 parabolas to intersect at 4 and even 3 points. But one of the parabolas would be on it's side. You can consider those cases.
I think that you did it correctly, that's correct.
<span>14.85 + 1.39x = 20
1.39x = 20 – 14.85
1.39x = 5.15
1.39 / 1.39 = 5.15 / 1.39
x = 3.70</span>
