an equation of a line perpendicular to the line represented by the equation y=-1:2x-5 and passing through (6,-4) is

Inga [223]

Whatever you intended to type before the 'x' . . . " -1.2 " or " - 1/2 " . . .
that's the slope of the line represented by the equation.

A line perpendicular to it has a slope with the negative reciprocal of this one.
So the perpendicular line would be

y = 0.8333 x (negative reciprocal of -1.2) + any number
or
y = 2 x (negative reciprocal of - 1/2) + any number

A company dyes two sizes of rugs. A small rug requires 8 hours for dyeing and a medium-size rug requires 12 hours for dyeing. Th

Nikolay [14]

Answer:

8x + 12y < 240

Step-by-step explanation:

If x equals the number of small rugs and y equals the number of medium rugs dyed, we would need to multiply both variables by the number of hours taken to dye each sized rug. It takes 8 hours to dye a small rug (8x), and 12 hours to dye a medium rug (12y).

Then, to find the total number of hours they dye them in, add the terms together.

8x + 12y

The company must dye the rugs in less than 240 hours, so we will use a 'less than' (inequality) sign (it cannot be 240, or any more than 240).

8x + 12y < 240
