How do I write an equation of a line that is parallel to 2x-3y=15

Mathematics
1 answer:
lina2011 [118]2 years ago
4 0
The line given is -2x + 3y = 15, so we must rearrange:

=> 3y = 2x + 15
=> y = 2/3 x + 5

These two equations are EQUIVALENT, but one is in slope intercept form, the other isn't.

So in this case, gradient is 2/3 (or 2 units up, and 3 units across).

And we know that parallel lines have the same gradient. Hence, the general equation for lines parallel to it will be:

y = 2/3 x + n

where n can be any number (positive/negative, decimal/fraction/integer) except 5, which is original line.

For example, y = 2/3 x + 2

<u>Answer:</u>

ΔLNM is proved as isosceles triangle. Below for explanation.

<u>Step-by-step explanation:</u>

We know that:

  • AMBX = Square
  • Squares have equal sides

Since AMBX is a square, AL must equal to BN because they are the extra lengths of the square. The lengths of the square are AM, MB, BX, XA.

  • Side of square + Extra length = Side of triangle

This can tell us that the two sides of the triangle are equal. We also know that if 2 sides of a triangle are equal, it is classified as an isosceles triangle. Hence, ΔLNM is proved as an isosceles triangle.

for a school fundraiser troy sold 28 bags of popcorn and 40 candy bars and made 282. jake sold 17 bags of popcorn and 20 candy b
VARVARA [1.3K]
Assuming the cost of a bag of popcorn is p and that of candy bars is b, then;
Troy ; 28p +40b = 282
Jake; 17b + 20b = 160.50
Solving the two equations simultaneously,
   20(28p +40b =282)
   40(17p + 20b =160.5)
we get;
   560p +800b = 5640
   680p + 800b = 6420 subtracting to eliminate b;
              -120p= -780
                     p = 6.50
Replacing the value of p in either equation to get b;
          17 (6.5) +20b =160.5
                         20b = 50
                              b = 2.50
Therefore the cost of a bag of popcorn is 6.50
