The equation of the line that contains diagonal HM is y = 2/3 x + 7.
nirvana33 [79]

Answer:

The slope of the line that contains diagonal OE will be = -3/2

Step-by-step explanation:

We know the slope-intercept form of the line equation

y = mx+b

Where m is the slope and b is the y-intercept

Given the equation of the line that contains diagonal HM is y = 2/3 x + 7

y = 2/3 x + 7

comparing the equation with the slope-intercept form of the line equation

y = mx+b

Thus, slope = m = 2/3

  • We know that the diagonals are perpendicular bisectors of each other.

As we have to determine the slope of the line that contains diagonal OE.

As the slope of the line that contains diagonal HM = 2/3

We also know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line.

Therefore, the slope of the line that contains diagonal

OE will be = -1/m = -1/(2/3) = -3/2

Hence, the slope of the line that contains diagonal OE will be = -3/2

What is 3x+1? They say its really easy and I don't know how.

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

Answer:  \textsf{x = - 1 / 3}

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

Given: \textsf{3x + 1}

Find: \textsf{The value of the unknown variable x}

Solution: In order to solve for x we need to isolate it with the first step being to subtract 1 from both sides and then we would divide both sides by 3 to give us the solution.

<u>Subtract 1 from both sides</u>

  • \textsf{3x + 1 = 0}
  • \textsf{3x + 1 - 1 = 0 - 1}
  • \textsf{3x = 0 - 1}
  • \textsf{3x = - 1}

<u>Divide both sides by 3</u>

  • \textsf{3x / 3 = - 1 / 3}
  • \textsf{x = - 1 / 3}

Therefore, the final answer would be that x is equal to -1/3.

Sawyer owns a bicycle shop. During one week, he sells b bicycles for
mihalych1998 [28]

To find the total revenue for any object, you simply multiply the price of the object by the number of units sold.

In this case, the revenue for helments would be 3*14, and the revenue for bicycles would be 125*b.

Knowing that total revenue was 917, we can form an equation:

125b + 3*14 = 917

125b + 42 = 917

Subtract both sides by 42:

125b = 875

b = 7

Sawyer sold 7 bicycles
