Answer:

y = -1/2x + 5/2 or y = -0.5x + 2.5

Step-by-step explanation:

perpendicular lines have reciprocated slopes (opposite signs and values)

y = 2x + 1 → y = (-1/2x) + b

plug in (3,1) to find b

1 = -1/2(3) + b

1 = -1.5 + b

2.5 = b

y = -1/2x + 5/2 or y = -0.5x + 2.5

Answer:

y = -1/2 x +5/2

Step-by-step explanation:

y = 2x+1 is in slope intercept form ( y = mx+b) where 2 is the slope

We want a line perpendicular

Perpendicular lines have slopes that multiply to -1

m * 2 = -1

Divide by 2

m = -1/2

The slope of the perpendicular line is -1/2

y = mx+b

y = -1/2x +b

Using the point (3,1)

1 = -1/2 *3 +b

1 = -3/2 +b

Add 3/2 to each side

2/2 +3/2 = b

5/2 = b

y = -1/2 x +5/2

Answer:

See below. No image this time.

Step-by-step explanation:

1.

  • P(2, 8) → P'(-5, 1), which it went 7 units to the left, and 7 units down. Here is the equation: (x - 7, y - 7).

2.

  • R(-4, -9) → R'(-4, -2), which went 7 units up. Here is the equation: (x, y + 7).

3.

  • M(10, -3) → M'(3, 4), which went 7 units left, 7 units up. Here's the equation: (x - 7, y + 7).

4.

  • K(7, 11) → K'(0, 11), which went 7 units left. Here is the equation: (x - 7, y).

2) Find the angle measures of a triangle if the first angle is thirty-one degrees more than
Charra [1.4K]

Answer:

4x+88=180

First angle is 54°

Second angle is 23°

Third angle is 103°

Step-by-step explanation:

Let x be the second angle. First angle is 31+x. Third angle is 2*(31+x)-5 = 62+2x-5 = 2x+57

All angles in a triangle add upto 180°

31+x+x+2x+57 = 180

4x+88=180

Subtract 88 from both sides,

4x = 92

Divide by 4,

x = 23°

31+x = 54°

2x+57 = 2*23 + 57 = 46+57 = 103°

Nana76 [90]

Answer:

6 pints of white paint she used to paint her bedroom walls.

Step-by-step explanation:

Joy uses 9.5 pints of blue paint + white paint.

Joy used 3.5 pints of blue paint.

So, white paint used = total paint - blue paint used

Plug in the known values into the equation.

White paint used = 9.5-3.5 =6 pints
