X - 42 is a straight vertical line passing through  -42 on the x-axis ( point -42,0)
so the slope is infinite .
Another line with same slope  and parallel to it would be x = 36.

A horizontal like with slope 0  is perpendicular to it  It would have equation y  any number  so y = 6 would be an example.

If y =-5 when x =12.5 find x when y =15
Naily [24]

Answer:

x = -37.5

Step-by-step explanation:

Set up a proportion so -5/12.5 = 15/x

Solve for x so -5x = 15(12.5) so -5x = 187.5 so x = -37.5

HELP PLEASE ILL MAKE YOU THE BRAINIEST What is the area of the regular polygon?
Fed [463]

Based on the calculations, the area of this regular polygon (hexagon) is equal to 24 m².

<h3>How to calculate the area of a regular polygon?</h3>

Mathematically, the area of a regular polygon can be calculated by using this formula:

Area = (n × s × a)/2

<u>Where:</u>

  • n is the number of sides.
  • s is the side length.
  • a is the apothem.

<u>Note:</u> The apothem of a regular polygon is half the length of one side.

Therefore, Length = 2 × 2 = 4 meter.

Substituting the parameters into the formula, we have;

Area = (6 × 4 × 2)/2

Area = 48/2

Area = 24 m².

Please help me 33/2 + 3y/5 = 7y/10 + 15
8090 [49]

We are given with an equation in <em>variable y</em> and we need to solve for <em>y</em> . So , now let's start !!!

We are given with ;

{:\implies \quad \sf \dfrac{33}{2}+\dfrac{3y}{5}=\dfrac{7y}{10}+15}

Take LCM on both sides :

{:\implies \quad \sf \dfrac{165+6y}{10}=\dfrac{7y+150}{10}}

<em>Multiplying</em> both sides by <em>10</em> ;

{:\implies \quad \sf \cancel{10}\times \dfrac{165+6y}{\cancel{10}}=\cancel{10}\times \dfrac{7y+150}{\cancel{10}}}

{:\implies \quad \sf 165+6y=7y+150}

Can be <em>further written</em> as ;

{:\implies \quad \sf 7y+150=165+6y}

Transposing <em>6y </em>to<em> LHS</em> and <em>150</em> to<em> RHS </em>

{:\implies \quad \sf 7y-6y=165-150}

{:\implies \quad \bf \therefore \quad \underline{\underline{y=15}}}
