For the equations, you could say numerous examples such as 3( 2h + (-3g) + 1). You could also do something like 3x1(2h + (-3g) + 1). Then draw an equilateral triangle by using a ruler and put 2h + (-3g) + 1 on one side. Then you could put 1 mark through each side of the triangle to show that they are all equal. When you simplify the Perimeter equation, you would get 6 h + -9g + 3 using the distributive property.

Solve F=D+Drt for t.....
Anuta_ua [19.1K]

Answer:

t = \frac{-D+F}{Dr}

Step-by-step explanation:

Step 1: Flip the equation.

  • Drt + D = F

Step 2: Subtract D from both sides.

  • Drt + D - D = F - D
  • Drt = -D + F

Step 3: Divide both sides by Dr.

  • \frac{Drt}{Dr} = \frac{-D+F}{Dr}
  • t = \frac{-D+F}{Dr}

aleksklad [387]

Answer:

<h2>D: y= -(1/3)x -3</h2>

Step-by-step explanation:

(3, -4)=(x,y)\\y=3x+2\\\\m_1 =3\\In\: perpendicular\: line ;\\\\m_2 = \frac{-1}{m_1} \\m_2 = \frac{-1}{3} \\m_2 = -1/3\\\\Substitute \:new\:values\:into\: ;y=mx+b\\\\-4 = -\frac{1}{3} (3) + b\\-4 = -1 +b\\-4+1 =b\\-3 =b\\Substitute \:new\:values\:into\: ;y=mx+b\\y =-\frac{1}{3}x -3
