Passes through (6 1) and is perpendicular to the line 3x-4y=2 standard form
Snowcat [4.5K]

Answer:

1⅓x + y = 9

Step-by-step explanation:

Convert the Standard Form of the given line to Slope-Intercept Form:

  1. -4y = -3x + 2 [Move -3x to the right side of the equivalence symbol]
  2. y = ¾x - ½ [Divide everything by -4]

Then, after getting your equation, take the OPPOSITE MULTIPLICATIVE INVERSE of ¾ [perpendicular lines have OPPOSITE MULTIPLICATIVE INVERSE <em>Rate</em><em> </em><em>of</em><em> </em><em>Changes</em><em> </em>(<em>SLOPES</em>)], which is -1⅓ [or -4⁄3]. After getting your slope, you can perform the action with your given ordered pair to find your y-intercept:

1 = -1⅓[6] + b

-8

9 = b

Now that you have your y-intercept, this is your new equation in <em>Slope-Intercept Form</em>:

y = -1⅓x + 9

We are not done just yet. The final step is to convert the Slope-Intercept Form of the line to Standard Form, and here is how it is done:

y = -1⅓x + 9

+1⅓x +1⅓x

--------------

1⅓x + y = 9 → Final equation

Mike ate 1 3 of a bag of peanuts at the game, and on the way home he ate 1 3 of what was left. How much of the bag of peanuts di
svlad2 [7]

Mike ate 1 / 3 of a bag of peanuts at the game, then there left

1-\dfrac{1}{3} =\dfrac{3}{3} -\dfrac{1}{3}=\dfrac{2}{3}.

On the way home he ate 1 / 3 of what was left, that is he ate 1 / 3 from 2 / 3 and this is

\dfrac{1}{3} \cdot \dfrac{2}{3} =\dfrac{1\cdot 2}{3\cdot 3} =\dfrac{2}{9}.

On the way home Mike ate 2 / 9 of a bag of peanuts.

Answer: Correct choice is D.

Simplify the expression: 2x – 3x (5x – 8) – 4r (x - 2)​
AVprozaik [17]
Answer: –4rx –15x^2 + 8r + 26x

Step by step:

= 2x + −15x^2 + 24x + −4rx +8r

= (−4rx) + (–15x^2) + (8r) + (2x+ 24x)

= –4rx + –15x^2 + 8r + 26x
