write an equation of the line that passes through (-1, 4) and is perpendicular to the line y=-1/3x+3

gladu [14]

Answer:

y= 3x + 7 Step-by-step explanation:

y= -1/3x+3 (so, gradient of this line is -1/3).

formula: gradient of line one x gradient of line two= -1 (applies for 2 perpendicular lines only).

So, m1 x -1/3= -1

m1= ( $\frac{-1}{\frac{-1} {3} }$ )

m1= 3 (gradient of perp line)

y=mx+c

4= 3 x -1 + c

7=c

therefore, y=3x+7 (eqn of the line perp to y=-1/3x+3)

Polygon C and polygon D are similar. The perimeter of polygon C is 192 inches, and the perimeter of polygon D is 48 inches. If o

Marianna [84]

Answer:

B. 2 in.

Step-by-step explanation:

First, put the two perimeters together to form a fraction.

192/48, which can simplify to 4/1

Now, following the order in which you put the perimeters (I used C/D,) set it equal to the sides.

$\frac{4}{1} = \frac{8}{x}$

Now, cross multiply. (multiply 1 and 8, 4 and x.)

$4x = 8$

Now, solve.

x=2 inches.

Find the value of d 2d - 5 = 17

tester [92]

Simplifying 2d + -5 = 17 Reorder the terms: -5 + 2d = 17 Solving -5 + 2d = 17 Solving for variable 'd'. Move all terms containing d to the left, all other terms to the right. Add '5' to each side of the equation. -5 + 5 + 2d = 17 + 5 Combine like terms: -5 + 5 = 0 0 + 2d = 17 + 5 2d = 17 + 5 Combine like terms: 17 + 5 = 22 2d = 22 Divide each side by '2'. d = 11 Simplifying d = 11
