It's better organized and if you don't use place value it's all mixed up

HELP PLEASE
nordsb [41]

Answer:

<h3>perpendicular line:    y = -¹/₆ x + 4¹/₃ </h3><h3>  parallel line:              y = 6x - 45 </h3>

Step-by-step explanation:

y=m₁x+b₁   ⊥   y=m₂x+b₂   ⇔    m₁×m₂ = -1

{Two lines are perpendicular if the product of theirs slopes is equal -1}

y = 6x - 7   ⇒   m₁=6

6×m₂ = -1        ⇒    m₂ = -¹/₆

 

The line y=-¹/₆ x+b passes through point (8, 3) so the equation:

3 = -¹/₆ ×8 + b must be true

3 = -⁴/₃ + b

b = 4¹/₃

Therefore equation in  slope-intercept form:

                                                     y = -¹/₆ x + 4¹/₃

y=m₁x+b₁   ║   y=m₂x+b₂   ⇔    m₁ = m₂

{Two lines are parallel if  their slopes are equal}

y = 6x - 7   ⇒   m₁=6   ⇒   m₂=6

The line y=6x+b passes through point (8, 3) so the equation:

3 = 6×8 + b must be true

3 = 48 + b

b = -45

Therefore equation in  slope-intercept form:

                                                     y = 6x - 45

How to calculate the percentage?
miv72 [106K]

\:  \:  \:  \:  \:

  1. <u>How to calculate percentage of a number. Use the percentage formula: P% * X = Y</u>

  1. <u>Convert the problem to an equation using the percentage formula: P% * X = Y.</u>
  2. <u>P is 10%, X is 150, so the equation is 10% * 150 = Y.</u>
  3. <u>Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10.</u>

  • <u>Multiply by 100 and add a percentage </u><u>sign</u>
  • <u>0.876 = 0.876 * 100 = 87.6%</u>

<h2><u>hope</u><u> it</u><u> helps</u></h2>
