Answer:

$5

Step-by-step explanation:

Magazine cost: 5$ each

Eraser cost: X$ each

Total cost is the number of items (1 magazine) times the cost of each item (5$). We don't know the cost of each eraser, so we represent that using a variable, X.

 

  • 1(5) + 4(X) = 25

 

  • 5 + 4X = 25

 

  • subtract 5 from both sides

 

  • 4X = 25 - 5

 

  • 4X = 20

 

  • divide both sides by 4

 

  • X = 20/4

 

  • X = 5

  • Each eraser cost 5$

Hope this helps :)

Subtract magazine from total:

25 -5 = 20

Divide by number of erasers:

20/4 = 5

Each eraser cost $5

Write the slope-intercept form of the equation that passes through the point (-3, 5) and is perpendicular to the line y = 1/5x +
aleksley [76]

Answer:

<h2>y = -5x - 10</h2>

Step-by-step explanation:

\text{Let}\\\\k:y=m_1x+b_1\\\\l:y=m_2x+b_2\\\\l\ \perp\ k\iff m_1m_2=-1\to m_2=-\dfrac{1}{m_1}\\\\l\ \parallel\ k\iff m_1=m_2\\\\=========================

\text{We have}\ y=\dfrac{1}{5}x+10\to m_1=\dfrac{1}{5}\\\\\text{Therefore}\ m_2=-\dfrac{1}{\frac{1}{5}}=-5.\\\\\text{Put the value of a slope and the coordinates of the point (-3, 5)}\\\text{to the equation}\ y=mx+b:\\\\5=-5(-3)+b\\5=15+b\qquad\text{subtract 15 from both sides}\\-10=b\to b=-10\\\\\text{Finally:}\\\\y=-5x-10
