"After 64 seconds, ABOUT HALF of the brands of milk chocolate are LIKELY to melt and NONE of the brands of Dark Chocolate are likely to melt"
Step-by-step explanation:
The right answer is
"After 64 seconds, ABOUT HALF of the brands of milk chocolate are LIKELY to melt and NONE of the brands of Dark Chocolate are likely to melt"
We can easily check this solution by seeing the time it took for each chocolate to melt in the attached picture.
After 64 seconds have passed, half of the brands of milk chocolate had already melted, but the dark chocolate time starts after 200s

Y = -3/4x + 9 ...eq( 1 )
Y = -1/2x + 8 ...eq( 2 )
<em><u>Subsituting </u></em><em><u>eq(</u></em><em><u> </u></em><em><u>1</u></em><em><u> </u></em><em><u>)</u></em><em><u> </u></em><em><u>in </u></em><em><u>eq(</u></em><em><u> </u></em><em><u>2</u></em><em><u>)</u></em><em><u> </u></em><em><u>we </u></em><em><u>get</u></em><em><u>, </u></em>
-3/4x + 9 = -1/2x + 8
-3/4x + 1/2x = 8 - 9
-3x + 2x/4 = - 1
- x = -1 * 4
x = 4
<em>Thus</em><em>, </em><em>The </em><em>value </em><em>of </em><em>x </em><em>is </em><em>4</em><em> </em>
<u>Therefore</u><u>, </u>
<em>Subsituting </em><em>the </em><em>value </em><em>of </em><em>x </em><em>in </em><em>eq(</em><em>2</em><em> </em><em>)</em>
Y = -1/2 * 4 + 8
Y = -2 + 8
Y = 6
<em>Thus</em><em>, </em><em> </em><em>The </em><em>value </em><em>of </em><em>y </em><em>is </em><em>6</em>
<em>Hence</em><em>, </em><em> </em><em>The </em><em>value </em><em>of </em><em>x </em><em>and </em><em>y </em><em>is </em><em>4</em><em> </em><em>and </em><em>6</em><em> </em><em>.</em>
The equation f(x)=x² + 2x is a quadratic equation, and it passes through the points (0,0) and (1,3)
<h3>How to plot the points for the equation?</h3>
The equation is given as:
f(x)=x² + 2x
Set x = 0
f(0)= 0² + 2(0) = 0
Set x = 1
f(1)= 1² + 2(1) = 3
The above means that the equation f(x)=x² + 2x passes through the points (0,0) and (1,3)
See attachment for the graph of f(x)=x² + 2x
