Jolly had 12 burgers from the start.
if his five friends ate 2, you'd multiply that and get 10, then you add how many Jolly ate, which is 12.
Answer:
y = 2x - 10
Step-by-step explanation:
Look at the attached photo for work
You just need to use the slope formula to get the slope and then the point slope formula to get the final equation.
She paid $97.23 for the top soil. You just have to multiply 1.75 by 55.56. However, if you wanted to do this without actually solving the problem, it’s a rather easy guess. Since you know 55 times 1 is 55, choose the closest answer to it. Sometimes when it comes to math you don’t actually have to solve the problem, just take an educated guess. :)
D is halfway between A and B
so the coordinates of D are (2,2)
E is halfway between A and C so the coordinates of E are (-1,1)
now you need to find the gradient/slope of DE and BC using the formula:

<h3>
<u>G</u><u>r</u><u>a</u><u>d</u><u>i</u><u>e</u><u>n</u><u>t</u><u> </u><u>o</u><u>f</u><u> </u><u>D</u><u>E</u><u>:</u><u> </u></h3>
SUB IN COORDINATES OF D AND E

therefore the gradient of DE is 1/3.
<h3>
<u>G</u><u>r</u><u>a</u><u>d</u><u>i</u><u>e</u><u>n</u><u>t</u><u> </u><u>o</u><u>f</u><u> </u><u>B</u><u>C</u><u>:</u></h3>
<em>S</em><em>U</em><em>B</em><em> </em><em>I</em><em>N</em><em> </em><em>C</em><em>O</em><em>O</em><em>R</em><em>D</em><em>I</em><em>N</em><em>A</em><em>T</em><em>E</em><em>S</em><em> </em><em>O</em><em>F</em><em> </em><em>B</em><em> </em><em>A</em><em>N</em><em>D</em><em> </em><em>C</em>
<em>
</em>
therefore the gradient of BC is -2/-6 which simplifies to 1/3.
<h3>
therefore, BC and DE are parallel as they both have a gradient/slope of 1/3 and parallel lines have the same gradient</h3>
