a path across a park is represented by the equation y=-2x+5. A new path will be built perpendicular to this path. the two paths cross at (-2,9). I identify the equation that represents the new path. ​

Answers

Answer:

y = ½x + 10

Step-by-step explanation:

Perpendicular lines have OPPOSITE MULTIPLICATIVE INVERSE RateofChanges[Slopes], so you need to have a slope of ½, like in the work shown below:

9 = ½[-2] + b

-1

10 = b

0.185 repeating as a fraction??

Answers

The number 0.185 repeating can be represented as the fraction 185/999 in its simplest form.

What is the fraction?

A fraction is defined as a numerical representation of a part of a whole that represents a rational number.

To convert this number into a fraction, we can use the following steps:

Let x = 0.185185185...

Multiply both sides of the equation by 1000 to move the decimal point three places to the right:

1000x = 185.185185...

Subtract the left side of the equation from the right side:

1000x - x = 185.185185... - 0.185185185...

Simplify the right side of the equation by canceling out the repeating decimals:

1000x - x = 185

Combine like terms on the left side of the equation:

999x = 185

Solve for x by dividing both sides of the equation by 999:

x = 185/999

Therefore, 0.185 repeating can be represented as the fraction 185/999 in its simplest form.

Are the ratios 25/45 and 15/27 proportional? Explain.

Answers

Write them out as a fraction then reduce them. If theyre the same then its proportional.

25/45 can be cancelled down to 5/9

15/27 can be cancelled down to 3/9

So no theyre not.

Answer:

Yes

Step-by-step explanation:

because when we smaller them like 25/45 divide by 5 and 15/27 divide by 3 it forms 5/9
