Write an equation for a line perpendicular to y = -5x – 4 and passing through the point (15,5)
3241004551 [841]

The equation for the line in point-slope form that passes through (15, 5) and is perpendicular to y = -5x - 4 is \mathbf{y -5 = \frac{1}{5} (x - 15)}

<em><u>Recall:</u></em>

The equation of the line can be written in point-slope form (y - b = m(x - a)) and also in slope-intercept form (y = mx + b).

<em><u>Given</u></em>:

  • the point the line passes through: (15, 5)
  • the line it is perpendicular to: y = -5x - 4

<u><em>Find the </em></u><u><em>slope (m):</em></u>

The slope value will be the negative reciprocal of the slope value of y = -5x - 4.

  • The slope of y = -5x - 4 is -5.

  • Therefore, the slope of the line perpendicular to y = -5x - 4 will be the negative reciprocal of -5 which is: 1/2.

<em>Write the </em><em>equation </em><em>in </em><em>point-slope</em><em> form by substituting m = 1/2 and (a, b) = (15, 5) into </em><em>y - b = m(x - a)</em>

<em />

  • Thus:

y -5 = \frac{1}{5} (x - 15)

Therefore, the equation for the line that passes through (15, 5) and is perpendicular to y = -5x - 4 is \mathbf{y -5 = \frac{1}{5} (x - 15)}

In a college parking lot, the number of ordinary cars is larger than the number of sport utility vehicles by 59.3%. The differen
frutty [35]

Answer:

27 SUVs

Step-by-step explanation:

Let number of ordinary cars be x and SUVs be y

We can write 2 equations and use substitution to solve for the number of SUVs.

<u>"The number of ordinary cars is larger than the number of sport utility vehicles by 59.3%"- </u>

This means that 1.593 times more is ordinary cars (x) than SUVs (y), so we can write:

x  = 1.593y

<u>"The difference between the number of cars and the number of SUVs is 16" - </u>

Since we know ordinary cars are "more", we can say x - y = 16

<em>We can now plug in 1.593 y into x of the 2nd equation and solve for y:</em>

<em>x - y = 16</em>

<em>1.593y - y = 16</em>

<em>0.593y = 16</em>

<em>y = 27 (rounded)</em>

<em />

<em>Hence, there are 27 SUVs</em>
