Do the equations y = -6x +4 and y = 4x + 6 have one solution, no solution, or infinitely many solutions
Black_prince [1.1K]

Answer:

One solution

Step-by-step explanation:

We know there is only one solution because the lines do not have the same slope, nor are they the exact same line.

So we know they must have just one solution.

Best of luck

Find the area and perimeter. Stuck on this one need help
masya89 [10]

9514 1404 393

Answer:

  • area: 114 square units
  • perimeter: 44 units

Step-by-step explanation:

The figure is a trapezoid with bases 12 and 7, and a height of 12. The area formula is ...

  A = (1/2)(b1 +b2)h

  A = (1/2)(12 +7)(12) = 114 . . . square units area

__

The length of side AB can be found using the distance formula:

  d = √((x2 -x1)^2 +(y2 -y1)^2)

  d = √((6 -(-6))^2 +(1 -6)^2) = √(144 +25) = 13

The sum of the side lengths is then ...

  13 +7 +12 +12 = 44 . . . units perimeter
