How do you know if two lines are parallel given coordinates only? How do you know if two lines are perpendicular given coordinat

es only? Give a real world example of parallel and perpendicular lines and explain why it is so important for them to be parallel or perpendicular.

Parallel lines have the same gradient, so use the given coordinates to find the gradients of the lines.

Perpendicular lines have gradients that multiply to give -1. So use the given coordinates to find the gradient, and multiply them.

Perpendicular lines can be found on the globe, where longitudinal and latitude lines intersect. It's important for them to be perpendicular as they are used to measure time and location through geographical coordinates, and since Earth is essentially a sphere with 360 degrees, the lines have to be perpendicular for measurement.

(I could be wrong!!! I found some answers online and implemented them here.)

Reduce to the simplest form. -9/6 + (-3/5)
creativ13 [48]

Answer:

-\frac{21}{10} or -2.1 (they're the same)

Step-by-step explanation:

  1. Simplify: -\frac{9}{6} + (-\frac{3}{5}) = -\frac{9}{6} - \frac{3}{5}  
  2. Find a common denominator. The LCM of 6 and 5 is 30, so multiply the numerator and the denominator by the same thing: 6 × 5 = 30, -9 × 5 = -45, 5 × 6 = 30, 3 × 6 = 18
  3. Write the new fractions: -\frac{45}{30} - \frac{18}{30}  
  4. Subtract: -45/30 - 18/30 = -\frac{63}{30} = -\frac{21}{10}

I hope this helps!

A scalene triangle has 3 unequal sides, so none of the sides are the same. A right triangle has one angle that is 90°, which is indicated by a little square. An isosceles triangle has 2 equal sides (it looks like an ice cream cone). And an equilateral triangle has 3 sides that are all the same.

The price of a mango at a fruit stand goes up 5 cents each month. The first month the stand was open, a mango cost $1.25. What w
Dahasolnce [82]

Answer:

$2.45        

Step-by-step explanation:    

Let x be the number of months.  

We have been given that price of a mango at a fruit stand goes up 5 cents each month. This means that price of mango in dollars after x months will be 0.05x (1 dollar=100 cents).

The first month the stand was open, a mango cost $1.25. This means that cost of mango in the x months after 1st month will be: 1.25+0.05x

Now let find the cost of mango in the 25 month by substituting x=24 in our expression because price will increase 24 times after 1st month.

\text{The cost of a mango be in the 25th month}=1.25+0.05*24

\text{The cost of a mango be in the 25th month}=1.25+1.2

\text{The cost of a mango be in the 25th month}=2.45

Therefore, the cost of a mango in the 25th month will be $2.45.
