Please help me it’s due tonight and I’m stuck on this question!!
solniwko [45]

Answer:

The length of the ramp is 7.3 meters.

Step-by-step explanation:

The length of a triangle's side must be less than the sum of its two other sides. It also cannot have the same value as its other combined sides.

7 + 2 > 7.3

2 + 7.3 > 7

7 + 7.3 > 2

<em>r</em> is also longer than 7 meters, so that leaves option b. as your answer.

Answer:

a) Infinite solutions

b) No solutions

Step-by-step explanation:

First, know the following:

If the graphs intersect, there's only one solution.

If the graphs are parallel, there are no solutions.

If the graphs are the exact same line, there are infinite solutions.

For a):

Change the first equation into a linear one.

  • 2x+3y=6
  • 3y=-2x+6
  • y=-\frac{2}{3} x+2

Change the second equation into a linear one.

  • 4x+6y=12
  • 6y=-4x+12
  • y=-\frac{2}{3} x+2

Boom. You have two equations which are equal. As stated above, graphs on the exact same line have infinite solutions.

For b)

They are already in linear form so hurray.

y=\frac{1}{5} x+2\\y=\frac{1}{5} x+10\\

These lines are parallel since they have the SAME slope but a different y-intercept. As stated above, parallel lines have no solutions.
