Answer:

  2

Step-by-step explanation:

We can solve for y to find the slope of the given line.

  x +2y = 2

  2y = -x +2 . . . . . subtract x

  y = -1/2x +1 . . . . divide by the coefficient of y

The slope is the x-coefficient, -1/2.

Any perpendicular line will have a slope that is the opposite reciprocal of this:

  -1/(-1/2) = 2

A perpendicular line will have a slope of 2.

Using the number line, determine which expressions have a value that is greater than –8. Select Yes or No for each expression. l
Nimfa-mama [501]
<h3>Answer:</h3>

yes

  • -6-(-6)
  • -4-(-7)

no

  • all others
<h3>Step-by-step explanation:</h3>

Doing what the directions say is generally a good idea.

Adding a number moves to the right; subtracting a number moves to the left. Subtracting a negative number is the same as adding its opposite.

The arrowhead end of the line in the figure is the end result. Two of them end up to the right of -8, that is, greater than -8.

What does -3+7y=5x+2y Equal<br> (I’m bad at math)
bogdanovich [222]

Answer: 22 /5

-3+7y=5x+2y

Step-by-step explanation:

Subtract 2y from each side

-3+7y-2y=5x+2y-2y

-3 +5y = 5x

Add 5 to each side

5y = 5x+3

Divide each side by 5

y = 5x/5 +3/5

y = x +3/5

Let x = -5

y = -5 + 3/5

y = -25/5 +3/5

y = -22/5
