Answer:
1) 17
2) 15 because then the associated lines would be coinciding
Step-by-step explanation:
1.) 17
2.)
<u>2x - 4y = 10</u>
<u>3x - 6y = r</u>
<u>Step 1</u>
First lets try to <u>substitute r with 10</u>
and that looks like
<em><u> *Look at the second image*</u></em>
<u><em>And it has No Solution because they are parallel </em></u>
<u><em>so we can cross out B and C</em></u>
<u>Step 2</u>
So lets try to substitute r with 15
and that looks like
<em><u>*Look at the First image*</u></em>
<u><em>It might look like there is only one line but there are actually 2 and they are on top of each other </em></u>
<em><u>So that means that they are not parallel but they are coinciding</u></em>
So we can cross A out and that means the answer is D
<u>Step 3</u>
So the answer is 15 because then the associated lines would be coinciding
